Blenheims over Magrun , 22 December 1941

Background

Following the retreat from the Gazala position the Desert Air Force quickly moved west in pursuit, and within days had operations going at Gazala and Mechili landing grounds which were used as staging and concentration posts from which to hit the Axis forces, in particular their air force, in the enemy rear areas.

The role of ULTRA

A major effort was made on 22 December to disrupt operations and destroy planes and ground assets on Magrun airfield.

ULTRA intercepts during the previous days had shown that the landing ground had become a major concentration area for the Axis air forces, and had also placed the battle HQ of Panzergruppe at Magrun[1], and noted that Luftwaffe supplies going into Magrun were considered inadequate, on 21 December. This was the short period during which Bletchley Park was reading the Panzergruppe communications almost in real time. 

In consequence, 13 Corps and the Desert Air Force command laid on two operations on the ground and in the air, to interrupt the Axis on the landing ground. This consisted of 13 Corps directing 22 Guards Brigade onto Margin late on 21 December, and 204 Group setting up multiple raids for 22 December. These operations on 22 December were therefore what would be called ‘intelligence-led’ today, in reaction to this information, and showed how quickly ULTRA intercepts could be turned into operational action.

In particular, a message from Fliegerfuehrer to his Chief of Staff had been intercepted, asking when additional fuel would arrive for the aircraft that were arriving at Magrun, and informing that i) the delivery on the Regia Marina submarine Micca to Benghazi had only been Italian fuel, and that 16,000 ltrs. of fuel that had arrived at Maraua, the previous HQ, had been entirely used up. It was therefore reasonable to presume that at any given moment the next day substantial numbers of Luftwaffe aircraft would be on the ground at Magrun, either delivering fuel, or arriving to be refueled, and constituting a major target.

On 22 December, the following attacks went in:

1. Night 21/22 December, night raid by Wellingtons. Results inconclusive.

2. Morning fighter sweep (see below)

3. Morning attack by Bostons, claiming four planes destroyed on the ground.

4. Afternoon attack by 270 Wing Blenheims, claiming 2 Ju 52 destroyed, 2 probably destroyed, and 2 more damaged, all on the ground.

5. Afternoon attack by Marylands (2 and 3 of Nos. 12 and 21 Squadron S.A.A.F. respectively), which fail to bomb due to the target being insufficiently covered by patchy cloud at 5-6,000 ft, exposing the unescorted Marylands to too high risk in a low attack.

Blenheims, from Nos, 14 and 84 Squadrons RAF and the Lorraine Squadron of the Free French Air Force, made a series of attacks on El Magrun on 21-22 December, which was being used extensively by the Luftwaffe to provide air support for their retiring ground forces during operation CRUSADER (Courtesy IWM CM2017)

Raids on Magrun Airfield 22 December

Magrun airfield was located 71km south of Benghazi, and was abandoned on 22 December. Prior to leaving there was still heavy activity on it, with crews and stores being removed. It had been used by the Regia Aeronautica, and the first mention of a German plane on the landing ground was not until 20 December, when the Luftwaffe started to occupy it during the retreat. It became the target of a major effort on 22 December. The landing ground had no facilities, but was closely located to the road, and protected by a fort to the north-east.

First went the fighters, a combination of Tomahawks from Nos. 112 and 250 Squadrons, out of Mechili landing ground, went to the air field for a ground strafing attack at 0940 hours. The famous No. 112 Squadron (with its Sharkmouth insignia) undertook one of the last operations with Tomahawks.

112 Squadron

A flight of 6 Tommies[2][3] led by Flight Lieutenant WESTENRA took MAGRUN aerodrome by surprise coming out of the sun. F/Lt. WESTENRA damaged a Ju 87 and with Pilot Officer BARTLE destroyed a Ju 87. P/o Duke destroyed a Ju 52 while he probably destroyed a Ju 87 with Sgt. CARSON. A further sweep in the afternoon produced nothing of interest and no enemy aircraft were seen.[4]

250 Squadron

7 a/c in conjunction with 112, 2 & 4 Squdns. made fighter wing sweep to Magrun aerodrome and ground staffed it. Sgt. Dunlow shot down a JU. 87 which was coming in to land – Sgt. [unreadable] damaged one in like circumstances. At least 4 fires were left burning on the aerodrome. A number of JU 52’s being destroyed.

The No. 2 Squadron S.A.A.F. report notes a successful strafing action, with 2x Ju 52 destroyed, 2x Ju 87 damaged, as well as 1x Ju 88 and curiously 1x Do.215 damaged[5].

112 Squadron LG122Pilots of No. 112 Squadron RAF grouped round the nose of one of their Curtiss Tomahawks at LG 122, Egypt. Those identified are, (left to right): Sergeant R F Leu, Pilot Officer N F Duke, Flying Officers J F Soden (on wing) and P H Humphreys, Squadron Leader F V Morello (Commanding Officer), Flight Lieutenant C F Ambrose, Flying Officer E Dickenson (killed in action 28 May 1942), Sergeant H G Burney (killed in action 30 May 1942), Flying Officers D F Westenra, J J P Sabourin (killed in action 6 October 1942, while flying with No. 145 Squadron RAF), N Bowker and J P Bartle, and Sergeant K F Carson. (IWM CM1820)

While the time isn’t clear, it is likely that the Douglas Bostons of No. 24 Squadrons S.A.A.F. went later in the morning, unescorted. It was the last mission of the year for the squadron.

22-12-41 Nine Bostons bombed aircraft on Sid-amud-el-Magrun aerodrome 60-70 aircraft (including 30 JU52’s) dispersed on NW side of aerodrome. 8x 500 HE bombs fell in and slightly short of dispersal area and 24x 250 HE among aircraft and one was seen to be burning on aerodrome on approaching target. 4x 250 bombs hung up slightly and overshot, falling edge of dispersal area. 7/10 cloud over target. Total bombs 8×500 and 28x 250. Total flying time 22.5 hours.

The second light bomber daylight raid on Magnum on 22 December was fairly typical of the period. It was meant to be a major effort by 276 Wing, putting into the air a large number of Blenheims from all its squadrons for two consecutive raids. The operation order is crisp and clear.

Group Captain, Commanding,

No. 270 Wing, R.A.F.

Fighter escort was provided by Nos. 2 and 4 S.A.A.F. Squadrons and Nos. 112 and 250 Squadrons RAF. The raid encountered two Me. 109F, but no engagement ensued. The fighters reported strong and accurate light AA fire.  

All six operational Blenheims from 14 Squadron accordingly left Gambut at 0515, and arrived at Gazala at 0605. The detailed record explains that due to problems with communication and cloud cover over the airfield only 3 aircraft arrived, the others returning. I suspect the issue was that the aircraft went to Mechili rather than Gazala landing grounds.

Therefore, 14 Squadron ultimately only put up three Blenheims for Magrun, ships 9656 J, 5950 V, and 5947 M, crewed by Wing Cdr. Buchanan, Sgts. Chaplin and Ball; Sgts. Willis, Young, and New; and Pilot Officers Wilbon, McKenny, and Sgt. Webster, respectively. 

Following the raid, the three planes returned to Gazala, from where they left at 1100 to return to base at 1445.

Proceeding to EL MECHILI where fighter escort was provided these 3 aircraft formed part of a wing formation. On the aerodrome at Magrun six Ju. 52’s and six 109’s were seen, and our aircraft at 1320 hours G.M.T. from 5,000 feet dropped 4x 250 lbs bombs each. Two Ju. 88’s[6] and one M.T. were seen to be hit, all the bombs fell in target area. Heavy slight A.A. was experienced, two of our aircraft were hit, but all however returned to base.

German records (kindly provided by Andrew from airwarpublications.com) show that the Allied cliaims on the while were reasonably accurate. They are given below as received. Total losses amounted to one Ju 88 reconnaissance, 3x Me109F, 2 x Ju 52 and 2x Ju 87 on this day.

– 22.12.1941: 2.(F)/123 Ju 88 destroyed by strafing at Sidi el Magrun [loss list]
– 22.12.1941: I./J.G. 27 Bf 109 destroyed by own troops at Magrun [loss list]

Waterlogged1

A Bristol Blenheim Mark IV, ‘U’ (serial number unclear) of No. 45 Squadron RAF, undergoes an engine overhaul at waterlogged Gambut, Libya, after violent rainstorms in November and December 1941 rendered many of the forward airfields unusable during Operation CRUSADER.

112 Squadron Pilots 

Three notable pilots  of No. 112 Squadron RAF, photographed on reaching the end of their tour of operations with the Squadron in North Africa, (left to right): Flight Lieutenant D F “Jerry” Westenra, Flying Officer N F Duke and Flight Lieutenant P H “Hunk” Humphreys. Each of them wears the top button of his dress tunic undone as the (unofficial) mark of the fighter pilot at the time. (IWM CM2504)

Westenra was a New Zealander from Christchurch, who joined 112 Squadron early in 1941, flying with them in Greece, Crete, and in the Western Desert where he was made a flight commander. He is reputed to have urged the adoption of the ‘Sharkmouth’ insignia by the Squadron in September 1941. At the conclusion of his tour in March 1942, he received the DFC for shooting down five enemy aircraft. In 1943 Westenra flew with No. 601 Squadron RAF in North Africa, and commanded No. 93 Squadron RAF in Italy. In March 1944 he was appointed to commandNo. 65 Squadron RAF during the Normandy Invasion, returning to New Zealand in September 1944.

Duke was posted to 112 Squadron in February 1941 after serving with No. 92 Squadron RAF in the United Kingdom. Despite being shot down twice, he achieved an impressive tally of eight confirmed victories in the Western Desert before leaving the Squadron in April 1942. He was then posted to El Ballah as an instructor at the Fighter School before rejoining 92 Squadron in the Western Desert in November 1942 and a adding further 14 victories to his total. In June 1943 he became Chief Flying Instructor at No.73 Operational Training Unit at Abu Sueir, but returned to operations as Commanding Officer of No. 145 Squadron RAF in Italy in March 1944. He returned to the United Kingdom in January 1945 with 28 victories to become a test pilot with Hawkers.

Humphreys joined 112 Squadron as a flight commander in November 1941 after serving with Nos 152 and 92 Squadrons RAF. Like Duke, he left theSquadron in April 1942 to instruct at the Fighter School at El Ballah before returning to operations with No. 92 Squadron RAF in early 1943. He later took command of this Squadron and led it to Malta, Sicily and Italy before another rest from operations in November 1943. In April 1944 Humphreys returned to Italy to command No. 111 Squadron RAF, and left for the United Kingdom in November 1944 on his appointment as Station Commander at RAF Castle Bromwich. He was killed in a flying accident in 1947.

The Lorraine Squadron in CRUSADER

The Lorraine Squadron in CRUSADER

Background

Just at the start of CRUSADER, Flight published an interesting article on the Free French Air Force, with some interesting pictures (if anyone can tell me what kind of a plane General Valin is standing in front of, I’d be grateful – I thought it was a Bf 108, but it has a fixed undercarriage, so that can’t be it). The article can be found at this link. The Flightglobal archive is generally very interesting, by the way.

Free French Blenheims

A Free French flight equipped with Blenheims had operated during the East African campaign earlier in 1941. In October 1941, this was upgraded to a squadron, which became the major contribution by the Free French to Operation CRUSADER.

It was the 1st Bombing Group, known as the Lorraine squadron, a Bristol Blenheim equipped light bomber squadron consisting of two flights. In the course of operations, it lost 1/3rd of its flying personnel killed, missing or wounded, including  its newly arrived commander in December, Lt.Col. Pijeaud, was killed on his first mission when his plane was attacked by Axis fighters.

After the withdrawal of Axis forces to the west, the Group remained on the Egyptian border, based on Gambut airfield. After helping the Axis on the way by bombing rear area installations such as El Magrun airfield halfway between Benghazi and Agedabia (see below), it engaged in the bombardment of the Axis border fortifications of Bardia and Halfaya (see this older post). In the middle of January 1942 it was withdrawn for refitting to Syria.

During the 16 days before the surrender of the Halfaya garrison, the Lorraine flew 300 sorties against it, from Gambut airfield. In fact, together with other light bomber units the amount of sorties climbed to a level prompting inquiries from Whitehall if this was really necessary!

Lorraine Squadron in Modern View

This French language site has some good information on the unit, including pictures. At this link you can find a nice colour profile of a Bristol Blenheim Mk.IV in Free French colours. Just ignore the statement that they were operating in the Western Desert in February 1942. Funnily enough, it appears Airfix (ah, bane of my youth) also did a kit of the Lorraine Blenheim (apparently its a good kit too – check the link through the picture below).

Towards the end of the CRUSADER battles, the Free French 1st Fighter Group Alsace started operations in the air defense of Egypt, based at Ismailia on the Suez Canal, having just been re-equipped with Hurricane I fighters. Some information on this can be found at this link.

The End Outside Tobruk – 4 December 1941

The End Outside Tobruk – 4 December 1941

Background

After two weeks of hard fighting, and two mistaken expectations of victory (see here), 4 December 1941 was the day Panzergruppe packed it in outside Tobruk. The war diary of 90.lei. Afrika-Div. notes how the division, together with the equally hard-hit Italian Bologna division[1] was expected to undertake another attack to clean the remaining enemy pockets of the Belhamed height and re-establish the siege ring. This led to a “dramatic exchange of words” between the GOC of the division and General Crüwell of the Afrikakorps at lunch time. In the end however, General Sümmermann got his way partially and obtained a delay of the attack from 1400 hours to 1600 hours. It never took place. At 1500 hours the order to retreat came and the battle outside Tobruk was lost.

0898

Unknown Command Post during the battle for the salient. Rommelsriposte Collection.

15.00 hours General Crüwell passes on order from General Rommel as follows:

The armoured corps retreats west into the area 30km west of el Adem. 90.lei.Div. holds its position and continues to close of Fortress Tobruk from the east and south-east. In this regard the division takes command of the Belhamed and from 19.00 hours Ed Duda. In this regard Gruppe Mickl is subordinated. 21.Pz.Div. takes care of establishing communications Mickl to Sümmermann. In the rear the division will be covered by Mot. Korps Gambarra in the area of Sidi Rezegh. This creates a corridor. Through this corridor, on the night 4 to 5 December, the whole of the artillery of the division will be moved to el Adem. Prime movers will be allocated. 

Following receipt of this order the intended attack is no longer considered[…]

22.15 hours a new order from Pz.Gr. that apart from small rear guards also the division will be pulled out of its prior positions. Positions Belhamed, ed Duda, to be held and later to pull pack on El Adem. To the south stands Mot. Korps Gambarra and protects against attacks from the right flank. This order is immediately transmitted to the troops.

Lt. Hollmann became the leader of the rear guards, which consisted of one section per company. These were to hold until dawn, feint occupation of the position, and then in the late morning hours retreat as well.[2]

Underscoring further the deflation of the day is the report by Artillerie Regiment 33, which participated in the second attempt to reach Bardia.

Advance on Sidi Azeiz and Rearward March via el Adem on 4.12.41

On 4.12. 15.Pz.Div. advanced from the area Zaafran on Sidi Azeiz.

Order of march (large units)

Tank battalion Ramsauer

II./A.R.33

III./A.R.33

The march was at first disturbed by artillery fire from the south, but from Gasr el Arid went without any noticeable events.At Sidi Azeiz the tanks in the van met weak enemy who retreated immediately. The II. and III./A.R.33 went into firing position immediately and took the fleeing enemy as well as the abandoned leaguer under ricochet fire.[3] An enemy battery returned fire but without major effects.

During the afternoon the rear march commenced, at first into the area of Zaafran. During the night it became known that the enemy had managed to connect with Tobruk. The division united with its supply columns in the area of the junction with the Zaafran track on the Trigh Capuzzo and at 02.00 hours on 5.12. broke through to the west. The artillery marched in the group of 15. Schtz.Brigade.[4] Apart from attacks by enemy bombers no special events.

What had happened was that the advance guard of 15.Pz. had run into 31 Field Regiment of 4 Indian Division, who were in no mood to entertain them. Their diary describes the inconclusive action.

4 December

Enemy reported clear of SIDI AZEIZ at first light and our O.P.s felt their way forward, finding no opposition. At mid-day 14 enemy tanks with guns and lorried infantry observed approaching SIDI AZEIZ. Tanks in close formation. C.O. ordered fire to be held which appeared to make the enemy uneasy. No doubt he wanted to confirm where our gun positions were. Tanks appeared to split up and attempt reconnaissance. Some spasmodic shelling. We engaged enemy A/Tk guns observed being toward across skyline and they withdrew. Finally enemy column and tanks withdrew, admitting defeat and apparently with nothing accomplished.

The loss of HMS Barham

The loss of HMS Barham

On 25 November 1941 one of the heaviest losses of life, and the only loss of a Royal Navy battleship to a submarine at sea, occurred off Bardia, when HMS Barham was torpedoed at extremely short range by U-331, and sank within four minutes. 862 men went down with her, and her end was filmed by a war correspondent on board one of the escorting destroyers. The footage is at the end of this post.

Barham

HMS Barham was at the time engaged in an operation to engage potential enemy convoys, together with the other two battleships of the Mediterranean Fleet, HMS Queen Elizabeth (flag) and HMS Valiant, escorted by nine destroyers. The battleships were providing distant cover to the light cruisers of Force B[1], engaged in searching for the German merchants Maritza and Procida (see also this link and this link). Once the news had come through around 1630 hours that Force K out of Malta had sunk these, the battleships turned for Alexandria.

Her complete service history can be found at this link.The BdU (Commander Submarines) noted in his war diary the rather jubilant:

U331 – 1 battleship torpedoed in the Mediterranean. A new beautiful success.

The Loss and Finding of HM/Sub Urge

Please see this earlier post for a false report of finding HM/Sub Urge, coming out in 2017, which is now corrected.

Reuters reports the finding at this link, while this German article has many good quality sonar pictures of the wreck, and the Royal Navy has good information here.

Now that it is confirmed that she is found, hopefully the relatives will then have some more knowledge on what happened to the crew. 

The History of HM/Sub Urge

HM/Sub Urge was, as the name indicates, a U-Class submarine, and a highly decorated one at that. Her very active wartime history is very well set out on U-Boat Net at this linkUrge was lost with 44 men on board, carrying 12 passengers apart from her complement of 32. The crew and passengers were very highly decorated, between them accounting for:

1x D.S.O. and bar

1x D.S.C. and bar

2x D.S.C.

1x D.S.M. and bar, twice Mentioned in Despatches

10x D.S.M.

4x Mentioned in Despatches

Operations and Successes

HM/Sub Urge conducted all bar one of her patrols in the Mediterranean. Of these, Urge conducted four patrols during Operation CRUSADER, on its 14th patrol damaging the modern Italian Littorio-class battleship Vittorio Veneto in an attack that led to the cancellation of the critical convoy operation M.41 in mid-December 1941, where Veneto was part of the distant escort, guarding the convoy from attack by Force K (see this earlier post).

While this attack by HM/Sub Urge was quite a success, it appears that the Admiralty was not too happy that Urge’s commander did not try to sink her, even if it would have been suicidal to do so. Nevertheless, Veneto returned to port without great difficulty, but would not undertake another mission for exactly six months, when she sortied on 14 June 1942.

Urge also carried out two failed attacks on merchants in this period.

1 April 1942 – HM/Sub Urge’s Biggest Success

Urge’s most famous victim was the Italian light cruiser Giovanni delle Bande Nere, a Condottieri-class light cruiser from 1930. She was lost with about half her crew when Urge put a torpedo into her 11 miles south off the island of Stromboli on 1 April 1942. She was the last survivor of her sub-class (Giussano) of four light cruisers. Somewhat confirming that the class was very vulnerable, she broke in two after being hit centrally by two torpedoes, and quickly sank.

The exact location of her sinking and two pictures can be found at this link. Delle Bande Nere took 381 of her over strength crew of 772 with her when she broke up and sank rapidly, having been hit while underway 11 miles south of the island of Stromboli, off Sicily. A very good account of her sinking can be found on Lorenzo Colombo’s blog at this link.

Loss of HM/Sub Urge

The loss for HM/Sub Urge now appears to be confirmed as mining, when she was just out of Malta on 27 April 1942.  HM/Sub Urge was being transferred out of Malta, together with the remainder of 10th Submarine Flotilla, for its new home of Alexandria. Malta had come under increasing pressure in the early months of 1942, and was no longer considered a viable naval base due to constant air attacks, which forced submarines to spend the day at the bottom of the harbour to evade bombardments.

HM/Sub Urge was sent to Alex with its full crew of 32, 11 additional naval personnel, and 1 war correspondent. Just a short distance outside La Valetta, she hit a mine on a newly laid, thus unknown barrier bow-on, and with her bow blown off plunged into the deep out of control and with no chance of survival for anyone on board. 

The German 3. S-Flottille (E-Boats) had dropped a new mine barrier (MT13) across the path she took to Alexandria just an hour before she left Malta on the last journey, and it is now confirmed that this barrier caused the loss of HM/Sub Urge.

Introduction

One of the enduring images of the desert war is that of the rapidly advancing Afrikakorps sweeping all before it. This is certainly what happened in April 1941, and it led to considerable gains of terrain for the Axis, and substantial losses in men and equipment for the Empire forces, and the siege of Tobruk. This advance was against clear orders given to Rommel, namely to await the arrival of 15. Panzerdivision in May 1941 before commencing any major operations.

Raids however (the Wehrmacht used the same term) were allowed. These were presumably considered useful in that they would keep the Empire forces off balance, and would deny them peace and quiet during which to prepare for their planned advance on Tripoli. Rommel commenced his raid on Agedabia, and when testing the Empire defense found it weak, and unleashed his forces for a deep penetration and with the aim to completely defeat the enemy in the western desert. This was of course of major propaganda value, and it has shaped the image we have of Rommel today, with a victorious German force (the Italians are normally overlooked) advancing rapidly, encircling and defeating all before them.

A Counterfactual Approach

Modern historiography however has not been kind about this rash advance in defiance of orders from Berlin, and the general view today is that Rommel was out of his depth and never really got to grips with the logistical challenges his theatre forced him to confront.

The official German history Das deutsche Reich und der zweite Weltkrieg considers this advance the original sin, which put the Axis forces into a logistically impossible situation from which they never recovered, while not achieving a decisive outcome, when the assaults on Tobruk in Apri and May failed. It is hard to disagree with this view, once one reads the Panzergruppe war diary appendices, which are a long story of supply concerns through all of 1941.

My view is that modern historiography is correct, and that the move towards the east and the conquest of Cyrenaica and Marmarica did fatally damage the ability of the Axis to sustain its campaign in North Africa. The terrain gained was worthless without Tobruk and while the losses inflicted were heavy, they were far from fatal, and both tanks and men could be replaced on the Empire side.

A counterfactual consideration

Of interest here is the counterfactual – what could have happened, had the advance not taken place? This post will provide some thoughts on the matter, based on the following assumptions:

1) The campaigns in Greece, Syria, Iraq, and Abyssinia proceed unchanged.

2) There is no change to the speed of the build-up or the force allocations on both sides.

3) The strength of the tank force on both sides is the decisive factor in the timing of any major operation.

4) Light tanks such as the Italian L3 series, the German Panzer I, and the British Vickers Mk. VI are ignored on both sides.

5) Only raids are undertaken on both sides, neither is trying to advance in strength with the intent to hold territory, and any tank losses from these are temporary or replaced.

6) The exact numbers of the tanks don’t matter as much as long as the ball park is correct. In particular for the Empire side, getting to the right numbers is very difficult, as they did not know themselves for much of the first half of 1941.

The tank balance to autumn 1941

First, without the advance, the forces facing each other in Cyrenaica are reasonably well balanced at the end of March. Including some replacements for ten tanks lost in the fire on the Leverkusen, by mid-April the Axis can field 75 Panzer III, 20 Panzer IV, 45 Panzer II, and 32 Panzerjaeger I, and two battalions of Italian M13/41 medium tanks, with about 100 M13/40 tanks between them. This is a total of 272 combat capable vehicles, facing 112 British cruisers[1], 60 captured Italian M tanks, and 40 I tanks, for a total of 212 tanks, of varying reliability. It is clear that this force balance does not allow the Empire forces to consider a successful offensive, and that they need to await a substantial force build-up.

By the end of May, the Axis will receive the full force of Panzerregiment 8 as well as the other divisional units of 15. Panzerdivision, with the last of the tanks reaching Tripoli in the first days of May. The Axis tank force now numbers 91 Panzer II, 153 Panzer III, and 40 Panzer IV, as well as 32 Panzerjaeger I and the 100 Italian Mediums, for a total of 416 vehicles. 

At the same time, the Empire forces also receive reinforcements by tanks being returned from workshops, and the Tiger convoy arriving in mid-May shortly after, which then enabled operation BATTLEAXE to proceed. On 7 May, prior to the arrival of the Tiger convoy, the Empire tank force, assuming the April battles did not take place, numbers 115 cruisers, 59 I-tanks, and 60 captured Italian M tanks, for a total of 234 vehicles, meaning that the Axis now has a substantial superiority in tanks fielded in North Africa. Furthermore, the Empire tank force relies still on tanks with high mileage, and captured tanks of dubious combat value for its advantage.

By the end of June the picture does change. The Italian tanks are reinforced by another battalion, bringing the total to 138 M13/40 tanks and the Axis total to 454. On the Empire side, further returns from workshops as well as convoy arrivals, especially Tiger convoy, add large numbers of cruisers, bringing the total to 303 available[2], and the number of I-tanks rises to 201, to bring the total to 563 tanks including the 60 captured Italian tanks. Still, over half of the Empire margin of around 100 tanks is accounted for by the captured Italian tanks, and as noted it is unlikely these would have had much value in battle, given the situation with spares and ammunition. Again, in my view this makes any major Empire offensive before the end of June unlikely, and a successful one practically impossible. This is before considering the pressures of having to deal with the desaster in Greece, the campaigns in Syria and Iraq, and the remaining resistance in East Africa.

The tank balance only shifts later in the summer, with the arrival of the WS9a and b convoys, and most importantly the arrival of the first M3 Stuart tanks directly from the US (detailed at this link). By September, there are 100 operational M3s in theatre, and 298 British cruisers[3], together with 298 I-tanks[4], and most importantly crews and support units had time to familiarise themselves with the new vehicle. Assuming the captured Italian tanks are now retired, the Empire tank force now numbers almost 700 vehicles, giving the Middle East Command a substantial tank margin, with which to plan and execute a substantial attack would be possible, for the first time.

Other considerations

Both sides benefit and suffer from the Axis not advancing to the Egyptian border. The Empire holds Benghazi and the airfields of northern Cyrenaica, forcing Italian convoys to take the westerly route via Tunisia, where they can more easily be intercepted. They do not need to supply a besieged Tobruk, and they do not suffer the substantial distraction of an Axis force on the border during the rout in Greece and Crete. It is in my view unlikely that the RAF could have done much to protect the forward area and the port of Benghazi during this period, given its commitment to and losses in Greece.

On the downside therefore, Benghazi is exposed to air attack, making it an unsatisfactory port for building up an army level offensive. It needs to be kept in mind that the supply of Tobruk worked because it was for an overstrength division that was not expected to be mobile. So while the pressure on naval assets is reduced, the Empire coastal convoys are now taking a more exposed and longer route to Benghazi, and need to deliver substantially more supplies. This adds to the pressure on the RAF, which is at the same time heavily committed in Greece.

Given the above, it is likely that overland supply would have been key to building up for an offensive and keeping the force in western Cyrenaica supplied. The overland route from Tobruk, which would have been the safest harbour, to Mechili and west of it is hundreds of miles. Apart from the lack of tanks, the need for trucks to cover this adds substantially to the supply difficulties for a further advance. Even to support a Brigade-size forces that far west of the railhead was estimated to have taken 2,000 trucks shuttling back and forth (see this earlier entry on the planning for the BENCOL advance during CRUSADER, at this link). I consider it likely that the Egyptian railway would have been extended to Tobruk in this scenario, at least easing the supply concerns.

On the Axis side, conversely, the supply situation is substantially eased. The distances over which supplies are carried are much shorter, coastal convoying is possible to Sirt, and a very good main road is available. It is thus likely that the building up of supplies can be accelerated considerably.

In terms of operational opportunities, the relatively open terrain south of Agedabia allows deep raids into the Empire rear that are hard to defend against. Vehicles and men can be trained thus, while not using them up too much. The Sommernachtstraum raid of 14/15 September is an example of what would have been possible. An outflanking move into the desert, a quick hit on the Empire rear, chaos, confusion, and then retreat behind the Marada – Agheila line.

In terms of defense, the position from Marada north is relatively strong, and harder to flank due to the presence of salt marshes. An attack in the centre is possible, but would channel the attacking force considerably and expose it to hits from the north and south, similar to what happened to 22 Armoured Brigade at the end of December 1941 at Wadi el Faregh. A defense in depth, with infantry in the line, and tank forces to the rear to back them up, would have the potential to savage any attacker.

Conclusion

The Empire forces were in no position to attack at Agheila or Marada prior to September, simply based on tank numbers, before even getting into considerations of supply, where the need to build up substantial supplies to support not just the initial attack but an advance on Tripoli, several hundred kilometers to the west, would have taken time. From early May to the end of June the Axis tank forces and supply position would have been far superior to that of the Empire forces, inviting an attack by the Axis. 

If Rommel had waited and stuck to his orders, he would have kept the initiative until the beginning of summer at least, and would have been able to choose where an how to attack. The Axis force build-up was considerably faster than that of the Empire forces, and shortening the supply lines by hundreds of kilometers, and not wasting precious fuel and ammunition as well as spares on the initial advance in April and the failed attempts at Tobruk would have given the Axis ample reserves to work with.

An Axis attack out of the Agheila – Marada position before the end of May, with the full force of three armored divisions and substantial logistical preparation, and a substantial superiority in tanks would have promised much greater success than the lightweight attack at the end of March, and could easily have carried the Axis forces through well into Egypt. This could have been planned to co-incide with the invasion of Crete, thus forcing the Empire to look into two vastly different directions at once.

This was in my view a missed opportunity due to the impatience of Rommel.
