  ARMED BOARDING VESSEL CHAKLA, UNDER BOMBING ATTACK IN TOBRUK HARBOUR, 1941-04-29. NOTE HER CAMOUFLAGE SCHEME, THE COLOURS OF WHICH ARE PROBABLY 507A (THE DARKER GREY) AND 507C. THE CHAKLA WAS SUNK AS A RESULT OF THE ATTACK. (STILL FROM A CINE FILM)

 2200 hours the area of Division Trento was under heaviest fire by naval artillery of heavy calibre.

1250 hours following order issued to Gruppe Herff:
“Occupation of track climbing up at Pt. 191 and Suleiman important. Protection has to be so strong in MGs, ATGs and single guns that it hold as long against enemy attacks until support from the rear arrives.” Operations order followed by courier officer on 29 April (see the same).

2200 hours reported Gruppe Herff: “South of line Sidi Omar – Sidi Suleiman 5km southeast Pt. 191 enemy secures with armoured cars and tanks, evade when we advance. Coastal plain up to 15km southeast of Sollum free of enemy. 
Security pushed forward up to 6km southeast Sollum across the track leading from the desert to plain.”

Replenishment of 5.lei.Div. by bringing in troops via air was announced by O.K.H.

[1]This was a joint German-Italian attack. The close hit was caught on film, and ABV Chakla (3,081t) was sunk as a result of the attack. Her sister ABV Chakdina was sunk on 5 December with heavy loss of life, when leaving Tobruk with POW on board, and the last of the three, ABV Chantala, ran on a mine outside Tobruk on 7 December 1941 and was lost.

D.A.K. War Diary Entry 27 April 1941

Weather: max. Temp. 19 degrees C

Arrival and departure of subordinated troops:

Arrived by air (personnel)

Staff 15th Rifle Brigade
Staff I./I.R.104
3./S.R.104
4./S.R.104

Arrived in the operational zone:

Staff company S.R.115

Arrived of Div. Brescia:

227th Company 4.7cm ATG

On the frontline of Tobruk continuous active movement at and behind the enemy positions, in some areas limited enemy advances and artillery activity. Noticeably weak air activity.

On Sollum front enemy has apparently pulled back towards the ridgeline 10km east of Sidi Suleiman with one reinforced battalion. No more contact with the enemy on our security line. Our reconnaissance was hampered by heavy losses of armoured cars during the recent combats.

1345 hours order issued to Gruppe Herff to take Point 191 and Sidi Suleiman at 1700 hours following our air attack with a strong assault patrol and to hold it (see that order).

2100 hours reports Gruppe Herff: “As ordered, posts have been pushed out at Sidi Suleiman – Point 191.”[1] The units foreseen for the attack on Tobruk were set in march from the Sollum front following dusk, as outlined in the order “concerning move of formations”. Gruppe Herff was reordered as follows.

In the area Capuzzo – Sollum Battalion Montemurro and one company Battl. Trento, Artillery Battalion Frongia. In Bardia 1 Battl. Trento. A.A.3 as mobile reserve 6km south of Bardia on the road Bardia – Capuzzo. Standing patrols in the line Sidi Omar – Sidi Suleiman – Point 191. Mobile reconnaissance against the enemy across this line towards south and east.

In line with radio communication of 27 April 1850 hours Gruppe Herff was also left with an additional company Kradschuetzen Batl. 15 and one light AA platoon I./18. These were readied as reserve north of Capuzzo to be at the call of Gruppe Herff.

Bombers of Fliegerfuehrer Afrika successfully attacked AA positions in Tobruk.

Elements of 15. Pz.Div. were sent by air to Bengasi. An application was made to O.K.H. for immediate transport to Gazala, since no column space was available to bring these up.

[1]Probably Halfaya Pass. Sidi Suleiman seems to be Pt. 205

Fuel Allocation Request – Artillery Regiment 33

There is a lot of talk about how the desert required higher fuel allocations than foreseen for the German forces, but very little evidence of how this worked out in detail. I have just now come across some information in my files, which I will post below.

First a bit of background. Fuel was by far the most urgent and heaviest (by weight) of items in the German supply requirements. In the context of the desert war, fuel was crucial – no fuel, no movement of anything. The armies in the desert were dependent on trucks for moving supplies, and no attempt to ameliorate the situation by using coastal shipping, railways, or pipelines (all of which were used), could do more than lessen the requirement. 

Fuel was needed to carry everything, including fuel. The further away from supply entry points an army got, the worse the ratio of useful load/fuel use got. In the German case, the Panzergruppe  Command estimated that 1kg delivered to the port of Bardia was equivalent to 6kg delivered to Tripoli harbour, which should be read that to deliver 1kg of goods from Tripoli to Bardia, 5kg of fuel were needed – in other words it was hugely inefficient. 

Furthermore, for any movement off the main coastal road (which was in quality comparable to European roads), fuel consumption went through the roof. Moving vehicles of any type in desert terrain was not easy on the fuel use.

Finally, German fuel logistics were based on the concept of Verbrauchssaetze (loosely: ‘consumption units’), which used a set unit of output to determine a supply requirement. For fuel, this was the amount of fuel needed to move the vehicle 100km of distance. For weapons, it was called Ausstattung, and was the ammunition quota needed to carry out about 3-4 days of combat. For those wanting to know more, you can have a look at this link.

Now, after this explanation, here is the short but informative request, translated from a captured document, and found in WO208/3173 in the UK National Archives in Kew:

REPORT OF PARTIAL FUEL REQUIREMENTS (10 DAYS)

26 September 41: Artillery Regiment 33 reports to the 15. Panzerdivision

The 3,100 liter allowed to the Rgt. for every ten days is insufficient. The Rgt. asks for a raise of the allotment according to  the following key:

Water supply: 1,850 liter
Ration collections: 650 liter
Post collection: 350 liter
Fuel, ammunition, and spares collection: 360 liter
Evacuation of the sick: 650 liter
Inspection drives: 320 liter
Battery chargers: 700 liter

Total: 4,880 liter

Some items of note here. AR33 was stationary during the period in question. It’s supply point was Bardia, while it was stationed east/south of Bardia. The high number of fuel requirement for evacuation of the sick may reflect the high incidence of sickness in Panzergruppe during this period.

A little analysis shows that the requirement was about 57% higher than the allocation. Water supply was by far the highest requirement, at 38% of the new requirement, and almost 60% of the original allocation. What is interesting is the high requirement for battery charging – not something one reads a lot about in the context of military logistics in WW2. It’s over 14% of the new requirement, and almost 23% of the original allocation.
