Most Difficult to Conquer

[Prussian to the Iron]

Ahem... no. You can actually traverse the Nile-Red Sea-Channel.

ahem....no you cannot traverse it. at least not with any faction i have played (including saba). you cannot go through it unless you own alexandria, and at that point you are already in a war with the ptolemies and are too busy to bother with saba.

but hey that still leaves the ports of Memphis,Diospoli , Petra, Ptolemais and Axem from which you can launch a naval invasion, no???

petra? my memory is foggy but i dont think they have a port in the arabian sea.

and unless you are arche seleukia or the ptolemies, you have to conquer many large cities to get those ports.
