Technically not a photograph in the book (No photos around yet), but rather an artistic rendering of the navy in the swamps. Though, I agree that if they had bayonets, they would have had them fixed. The Army had adapted to using a bayonet charge after a volley or two to chase the Seminoles away. It was a sound tactic. The Seminoles did not take very good of their weapons and usually after firing a time or two, the guns would be fouled and they would retire. By trained troops charging with fixed bayonets towards the Seminoles, that might have had fouled guns with no bayonets, they would run that much faster away from the battle and the U.S. troops would take the field. For the navy, they never knew who might pop up and shoot or attack them from behind any nearby bush or tree. I'd move through the bush with fixed bayonet too.
