Maybe you'd like to enlighten me here, what forward ports are you talking about? Tobruk is the last port of any real note before you hit Alexandria, anything between the two is basically going to be what the ships themselves can unload.
Again though, these places have piers, and pretty much nothing else, so the ships are going to have to unload themselves, so unless the ships have cranes you're getting nothing heavier than a man can carry.When the alternative is 2000km on a truck even little places like Mersa Matruh, Sidi Barrini and El Dabaa become useful ports on occasion. Not much mind you but, I bet commanders deep in Egypt would really appreciate a few hundred tons of stuff dumped at these little places once in a while.
