I did not check the text thoroughly (for finding spelling errors or suggesting more elegant expressions), but i can say, that i like the choice of individual topics in your description.
Still, i have three minor suggestions for the 1311-campaign description.
1. Aegean Sea not Egean.
2. Tyrrhenian Sea not Tirrenian
3. I would mention their close connection with the city of Konstantinopolis. There was a comparatively big "foreign quarter" which was almost dominated by the Genoese and respresented their base of operations for the black sea trade. (as a side note: The greek alphabet knows no C. They use the letter Kappa for it=K. I can be a smartass, dont you think?
