The Crucifixion of Constantine the 11th

Constantine the 11th was trying to marshal public opinion in western Europe and force. Byzantine had survived intact cohesive and expanded so they felt that they had a superior paradigm. The Genovese contingent that did come were superb there were 700 of them and they repelled every Ottoman attack at the most vulnerable part of the walls until their leader was killed then they collapsed on the last day of the battle. They could have saved Constantinople by sending 3,000 men from Britain what would three thousand wouldn't have taken much is what i'm saying?
