Until now I believed that a total of 54 tanks tanks had been sent from Italy to the Afrikakorps on the M.43 convoy on 5 Jan 42. Jan very kindly sent me the loading lists for the convoy. From these, I can ascertain that the actual number was 56 tanks, not 54. Of these there were 47 mediums (37 Mk. III, 10 Mk. IV), and 9 light (Mk. II) tanks. So far, so good in the accounting errors department.
Now however, until today I believed that the next tank shipment was the operation T.18, which delivered a similar number of German tanks. Instead, in the loading lists I have now come across the lists for the German navy lighters (Marinefaehrpraehme, MFPs), which operated out of Palermo, where they were constructed. On 5/6 Jan, MFPs 152 – 159, a total of 8 lighters, were loaded with 24 medium tanks, 15 Mk. III, and 9 Mk. IV, to go to Tripoli.
The trip took them maybe 2-3 days, so this would mean that by about 10 January, a total of 71 new medium tanks had been received in North Africa.
UPDATE 15 June 2012: The MFP convoy was delayed due to a lack of escorts and weather, and only arrived at the end of February, after staying at Palermo for a while. The Panzer III on this convoy were the first ‘Specials’, with the long 50mm gun to be sent to Africa.
For the next trip, operation T.18, and the single runners Wachtfels, Atlas, and Trapani (which carried 10/4/4 tanks for a total of 18) it appears that tanks sent were 3/60/15/2 (Mk. II/III/IV/command tanks), plus 4 undefined, for a total of 84 tanks, of which 66 were on T.18. This convoy is normally given with 71 tanks for the Germans, and a total of 98 tanks (presumably including the Italian tanks).
UPDATE 15 June 2012: Atlas did arrive on 23 January, while Wachtfels only arrived on 23 February, and Trapani only on 7 February probably again due to lack of escorts.
In any case, this would make the reinforcements to Panzergruppe during January 12 light tanks, and 152 mediums/others (112 Mk. III, 34 Mk. IV, 4 undefined, and 2 command tanks).
Update 15 June 2012: given the above corrections, the number would drop back to the original 56 tanks sent with operation M.43.
I would like to see if this can be confirmed?
