Nope, they sent ships across med all the time. As for fuel, often it gets captured. Also a city that size would be impossible to destroy all fuel. remember civilian fuel is also to be found.
Tanks sent to Africa.
So, if I can add them up right for once, 25 Pz I, 120 (2) Pz II, 727 (82) Pz III, 328 (77) Pz IV, and 31 Tiger. Note that of the 1,393 recorded as shipped, only 149 were lost in shipping to enemy action (the 13 lost in March 41 were to a shipboard fire), or just over 10 percent. OTOH note that half those shipped as critical reinforcements to Pz.A.O.K. Afrika in December 1941 were lost.
Key word is "shipped".
