The Catholic fleet fought valiantly against the Turkish fleet, but my information has always been that the Christian fleet was older, slower and far less maneuverable than their Moslem counterparts. It was also a patchwork of ships from different navies, (Spain, Genoa, Venice), unlike the battle hardened, much experienced Ottoman fleet.
While I understand that historians tend to disagree on some facts, everything I've ever read about Lepanto shows it was a true miracle that the makeshift Catholic fleet routed the most powerful navy in the world, the mighty Turkish fleet, and sent most of their ships to the briney deep. This miraculous naval victory stopped what would have been a frightening Moslem invasion of Europe.
Today is the Feast of Our Lady of The Rosary.
Pray The Rosary today. In our war against Moslem Aggression and Terror our Lady is one of our staunchest allies. May she once again propel us to victory.
