Ah, yes, I was not including DeGrasse's men. Likely the fleet had roughly 25,000 crewmen. This was an all out French naval effort. Worked just fine.
Was trying to figure out how I had missed such a large number of French infantry, artillery, cavalry, etc.!!! Logistics would have been real difficult for a force like that there and then.
I believe that french ships of the line during that time had crews of around 800. That's a lot of men in 37 ships. ;-)
