The Mosquito That Saved Canada?-- Part 2: Chauncey's Malaria and Slow Movement

Allen Taylor in his "The Civil War of 1812" said that in July 1814, the newly-built U.S. warships gave Lake Ontario's naval supremacy to Chauncey, who wanted the honor of defeating the British under James Yeo, himself.

As such, he wouldn't let a subordinate take the fleet out until he was well enough to do it himself.

Army officers at Sackets Harbor, the U.S. naval base, denounced Isaac Chauncey saying, "There was a time opportunity of fighting and winning the long wished for battle, but lost because the only man in the fleet who was not ready was its commanding officer."
