Luftwaffe Appreciation of RAF Strength in North Africa, 20 November 1941

The item below is from the UK National Archives. It is an ULTRA/Enigma intercept, and I am comparing it with the actual RAF strength (another National Archive file kindly provided by Michele Palermo) for the same week. There are some assumptions in there which I’d happily correct, if someone knows better.

  1. Operational Units
    1. Single-engine fighters: 19 fighter squadrons with 450 – 500 Tomahawks and Hurricanes, of which at the moment 390 are in the front area, according to air photography. [actual: 17.5 squadrons and one flight of Fleet Air Arm Martlets, with another 4 more forming, 280 operational with another 394 operational in 14 days – so this is a serious over-estimate by German intelligence]
    2. Heavy fighters: 3 squadrons with 60 Beaufighters, at least 1 squadron of these in the front area. [actual: 1 squadron with 16 aircraft, with another 3 forming, and 8 more aircraft becoming operational in 14 days – another serious overestimate]
    3. Day bombers: 12 squadrons with 200-250 Maylands and Blenheims, of which at the moment about 170 are in the front area according to photography. 1 squadron, equipped with Boeing Fortress I aircraft, probably being formed in the Delta area. The greater fighting value of the Maryland as opposed to the Blenheim permits its employment as an auxiliary heavy fighter: low-level attacks and, above all, attacks on transport aircraft have frequently been successfully carried out (armament: 4 fixed MG’s firing forwards, 2 firing backwards, and in addition one moveable twin MG firing upwards and one firing backwards: this has been established from captured aircraft.) [actual: 9 squadrons of light bombers with 2 squadrons and 1 flight of Maryland/Blenheim reconnaissance, with a total of 144 bombers and 36 reconnaissance operational; none forming, and another 193 light bombers becoming operational in 14 days. 3 Fortresses only, which were on special assignment. Also half a squadron of Boston III active with 8 planes, with the half forming, and 15 Boston III to become active in 14 days – this is a reasonably accurate estimate; regarding the use of the Maryland as a heavy fighter, it rather appears to me that (with one exception I am aware of), Blenheims served in this role]
    4. Night bombers: 5 squadrons with 125 Wellingtons, night attacks on Cyrenaica are carried out every night, aircraft starting from Suez Canal area, with advanced landing grounds in the Western Desert (gliding attacks and flare-dropping carried out). [actual 5 squadrons with 100 planes operational and another 22 to become operational in 14 days no squadrons forming – this is an almost perfect estimate flare dropping however was carried out by Fleet Air Arm Albacores, which are not included in this strength report]
    5. Transport aircraft: 2 transport squadrons with 25 Bombays and/or Valentias and 20 Lockheeds. 6 Bombays were employed on night 16-17/11 to drop parachute sabotage detachment in Cyrenaica (this is confirmed by the shooting down of one aircraft and the papers recovered from it). [actual 2 squadrons with 24 Bombays/Valentias operational and another 4 to become operational in 14 days, no squadrons forming; 1 squadron with no Lockheed/Douglas active, and another one forming, with 16 planes to become operational in 14 days – again a very reasonable estimate)
    6. The shortage of personnel existing after the units have been brought up to strength as regards material seem to have been overcome. It must be assumed that there exist strong reserves in aircraft parks for fighter and bomber units, since there has been a constant flow of supplies by air to Africa (U.S.A. material) and via Mediterranean (English material) (cf. air photograph of aerodrome 25 km west of Hedouan. [this is a correct interpretation of the situation]
  2. Scale of Effort

    Night bomber units since 1/9/41, regularly at about 15 per cent daily. It is probable that with the increased scale of effort since early November the maximum possibilities of these units have been reached. On the other hand fighter and day bomber units have been carefully withheld up to the beginning of the month. Their present increased scale of effort is normal, having regard to the situation (scale of effort since … at the moment reaches at the most 25 per cent of the actual strength). It thus appears that scale of effort in present form is possible for some time ahead, and may even rise for a while.

Actual scale of effort:

  • Assuming 2 sorties per day for single-engine fighters, the capacity usage was 10% in this week, although that is a big if, since 521 of the 673 (plus 18 Hurricane recce and 16 Hurribomber sorties) sorties of all fighters are unspecified and could include Beaufighters and Blenheims. For the Beaufighters (assumed 1 sortie), usage was 26% of capacity, 29 sorties.
  • Assuming 2 sorties per day for Blenheims and Marylands, the effort was about 9%, 185 sorties (plus 5 Blenheim fighter sorties) with 144 operational planes, but there are also 64 unspecified bomber sorties, some of which will be Fortresses, some others Wellingtons and light bombers.
  • For the reconnaissance Blenheims and Marylands, usage was only 7%, assuming one sortie per day as capacity. A total of 18 sorties was made. But there are another 23 unspecified sorties.
  • Assuming (based on nothing but my own thoughts, if someone knows Luftwaffe capacity assumptions, please let me know) total capacity is 1 sortie per day for the Wellingtons, the effort in this week was about 21%, at 148 sorties compared to 100 operational planes.
  • For the transport fleet, utilization was also low, at 9% (assuming 1 sortie per day), 15 sorties of Bombays are recorded]

The numbers appear to show a very strong focus on the initial gaining of air superiority. For example, in the following week, the Blenheims and Marylands had 265 sorties with unchanged operational numbers, a rate of 13%. Wellington sorties remained practically unchanged, while fighter sorties increased to 777 on unchanged numbers, or a rate of 20%. Unspecified bomber sorties tripled however, so the actual utilization was higher.

Compared to the Luftwaffe expectation, the Desert Air Force was operating at a low capacity rate, if the assumptions are correct. This is partially explained by the longer distance planes had to fly to get to their area of operations, I guess. But there are also questions raised e.g. by Australian Wing Cdr. Geddes in a special report, about the efficiency of the ground crews.

A day in the life of the Luftwaffe – Operations report by Fliegerfuehrer Afrika 23 Nov. 41

Introduction

This operations report was sent on 23 Nov. 41 at 1730 hrs from Fliegerfuehrer Afrika Ic (intelligence officer) to Fliegerkorps X in Greece, and ITALUFT, the German Luftwaffe staff in Italy.

The report was intercepted by the British decoding teams and decrypted at Bletchley Park. It can now be found in the National Archives in Kew, London. I have left the report in the original text, annotated it, and provided a glossary below. I also re-ordered it according to time.

Fliegerfuehrer Afrika Operations Report 23 November 1941

0401 hours

1 Ju.88 of the AFRIKA Kette carried out recce of the tracks BIR EL GUBI – GIARABUB as far as SIDI OMAR. No enemy M/T observed. N.E. of BIR EL GUBI a concentration of about 100 M/T.

0540 hours

2 Bf. 110 of Stab Stuka 3 on recce S. of DERNA as far as 30 degrees N. 1 Bf. 110 brought confirmation of the 2 field aerodromes. 1 Bf. 110 missing. (1)

0550 hours

15 Ju.87 of II/StG2 carried out attack on tanks and M/T concentration E. of BIR EL GUBI, with 5.5 tons of H.E. bombs accurately placed in the target area. Very strong fighter defence: 3 Ju.87 missing, 1 Ju.87 made forced landing. 1 Ju.87 crashed on aerodrome, crew escaped by parachute.(4)

0555 hours

18 Ju.87 of I/StG1 attack on field fortifications and a battery position E. of BIR EL GUBI with 6.05 tons of H.E. bombs: bombs on target: effect not observed on account of strong fighter defence: 2 Ju.87 missing. 1 Ju.87 made forced landing, crew wounded but rescued. (2) (3)

0601 hours

1 Bf.110 of AFRIKA Kette in BIR HACHEIM to BIR EL GUBI and BAB ES [??} E. of BIR EL GUBI concentration of ?40 M/T. Otherwise nothing observed. At 0622 hrs [?] Bf.110 of III/ZG26 broke off attack on concentration near BIR EL GUBI as fighter protection was not assured.

0735 hours and again at 0802 hours

1 Ju.88 of the AFRIKA Kette on photographic recce of roads, railways and aerodromes SIDI BARRANI to EL DABA: heavy railway traffic at railhead: aerodromes only partly covered on account of heavy cloud.

0945 hours

11 Bf.110 of III/ZG26 broke off low-level attacks S. and E. of BIR HACHEIM on account of contact with 30-40 Curtiss fighters. (5)

1140 hours

In square 6231 3 destroyers and 1 small merchant ship, course west.

[No time]

I/ and II/JG27 shot down 10 enemy a/c on freelance patrols and while escorting Stukas. 1 Bf.109 missing, 2 Bf.109 made forced landing.

 

Notes

  1. There was only one field aerodrome in the area, Landing Ground 125, occupied by Hurricanes of No.33 Squadron and Blenheims of No. 75 Squadron
  2. This was likely on 1 South African Brigade which was in the area, ‘masking’ Bir el Gubi and the Ariete division position there. From memory I believe that these attacks were not very effective, even though they were unpleasant.
  3. A loss rate of 20% per sortie must have been extremely worrying.
  4. 33% loss rate.
  5. This, together with the two preceding notes, shows that while the Desert Air Force may not have had the number of kills of its adversary, it did achieve its operational objective on this day, which was to inflict losses on the enemy strike force and keep them away from their target, or at least reduce their efficiency.

The new war in Libya

This entry is not about Operation CRUSADER, but rather what is currently going on in the country, and it is going to be a bit of a rant.

It is weird that the places one comes across so often in historical studies are suddenly news items relating to another war. Little seems to have changed, and the key to Tripolitania and Cyrenaica is still Marsa el Brega, and Ajdabiya.  Also many of the other places that have played such a prominent role in CRUSADER – Tubruq, Benghazi, the airport at Benina. The pictures of burnt-out vehicles along the coastal road seem like flashbacks into the past of 70 years ago. Then Morris trucks, Lancia Ros and Opel Blitz – today Toyota pick-ups.

It has been infuriating to see the limp-wristed response of the west to the brutal way in which the Libyan regime has tried (and is likely to succeed) with the crushing of the uprising. What is now being tried is in my view likely to be too late, and will carry far more risks. I hope not, but I am pessimistic. Over the last few days, while the news from Japan buried the news from Libya, my heart has been sinking.

As far as the UK goes, I wonder what went on at the Cabinet meeting that just closed. Did anyone raise the point of good it would have been to not have decommissioned HMS Ark Royal and the Harrier squadrons? What a stupid decision that now looks to be. And no vote in parliament until Monday… Unbelievable.

One thing to hope for is that this will change the way people look at the French. I think at present the French Armee de l’Air is a major part of the only hope the rebels have, since they will be able to engage quickly, and I hope they do.

As for my own country, Germany, they can of course always be relied on to make grandiose statements and let other nations do the fighting. I wish Westerwelle would just put a sock in it. Another wish that is likely to be disappointed.

Good luck to the rebels, they will need it. I still have a lingering hope that maybe next year I will be able to visit a democratic Libya to finally see the places I have read about so much.

’We will never surrender. We will either gain victory or die!’ Sheilkh Omar al Mukhtar, murdered by the Italian regime after leading the resistance of Libya against Italian occupation in the 1920s and 1930s.

Operation CRUSADER in the News – 20 November 1941

Jon found that the NZ National Archives have digitised their newspaper collection and made it searchable. I went into it to have a look at the first mention of Operation CRUSADER.

The articles below cover the start of the operation:

British Advance in Cyrenaica – 50 miles penetration

“On the March” – New Zealand Troops

RAF in Lybia

Trial of Strength in the Desert

If you follow the Evening Post through the next days, there are some good articles and illustrations, which give a good feeling of the way the war was seen at the time.

New Zealand of course had a lot riding on the operation. It was the first time the New Zealand Division was participating in an advance against the enemy, and there was understandable apprehension based on what had happened in Greece and Crete.
