Convoluted Supply

Below a short ULTRA message that shows how complicated life got in terms of keeping the Axis forces in North Africa able to fight, after about three weeks of the CRUSADER battle. This was a period when shipments by merchants were reduced due to the heavy losses which had been suffered recently, and destroyers were employed as a costly expedient.

Dept. for AFRICA Transport has arranged for the delivery of most important supplies for AFRICA to PATRAS and SUDA BAY: from there, they will be sent on, partly on destroyers, and partly by air. Dept. for AFRICA Transport will direct freighters and destroyers to PATRAS, or SUDA BAY (as the case may be): ALBATROS is available for the journey to PATRAS. AMSEL for SUDA BAY: arrival probably not before 5/12.

Cargo of AMSEL:
G.A.F.: 353 cubic metres B4
Army: 90 tons M/T fuel, 400 tons ammunition (of which part has been unloaded at ARGOSTOLI).

Cargo of ALBATROS:
G.A.F.: 1,396 cubic metres B4, 96 cubic metres Rotring, 334 tons Flak ammunition, 271 tons equipment, including 25 (illegible), 100 auxiliary tanks, 43 cases Flak gun barrels (2 cm), 6 cases Flak gun barrels (3.7cm), 19 bottles accumulator acid, 40 a/c tyres, 130 tons canteen supplies, 69 tons bombs.

S.S. Sturla is to move to and fro between ALBATROS and AMSEL, to make up the AMSEL’s cargo. Further freighters are intended to be sent: times of departure and cargo lists will be issued in due course.

Air transport for G.A.F. supplies is required only for B4, a/c engines and Flak gun barrels. Of the army cargo, the Panzer ammunition is urgent. We request list of amounts of supplies sent by air or transhipped on to destroyer, so that supplies can be sent forward punctually.

Should destroyer arrive in SUDA BAY before the BELLONA, then they will (in accordance with orders of Dept. for AFRICA Transport, and SULTAN) be specially available for supplies of B4 to AFRICA.

Note:
ALBATROS = Wachtfels
AMSEL now thought to be BELLONA

A few days later further items were decoded, stating that Wachtfels had moved to Patras from Brindisi, and that it was now to transship directly onto destroyers (presumably at Patras). While saving time, by cancelling the transfer via S.S. Sturla, and by allowing the higher speed of the destroyers to come into play for the whole stretch from Patras to Benghazi, rather than have a slow merchant go to Suda from Patras, this was very costly in terms of fuel. Furthermore, it was now stipulated that the AA gun barrels were to be sent by air.

Patras at the time was also an important transshipment location for fuel to be loaded from ships to airplanes operating from close-by Araxos airport. This was more efficient, since the distance Araxos – Derna was only 394 miles, while a trip via Maleme would have brought the total distance to about 450 miles, and required another landing/take-off (thanks to Great Circle Mapper for this data). While I have no certain information on this, I would presume that the Ju 52 could easily carry its maximum payload over this distance, and might even be able (depending on wind) to return without refueling, as long as the return flight was empty, saving even more fuel in Africa.

G.A.F. = German Air Force
B4 = type of aircraft fuel with lower Octane rating.
M/T = motor transport
Rotring = not known, probably lubricant?
a/c = aircraft
