The Confederates lost two key commanders, Mouton and Green, and suffered casualties they could not afford. Perhaps more importantly, relations between the aggressive Taylor and cautious Smith were permanently damaged by their disagreement over Smith's decision to remove half of Taylor's troops following the Battle of Pleasant Hill. The lost opportunity to capture the entire Union fleet as it lay helpless above the falls at Alexandria haunted Taylor to his dying day; he was certain that Smith had robbed him a chance to cripple the Union forces. The arguments between the two generals resulted in Taylor's transfer to command of the Department of East Louisiana, Mississippi, and Alabama soon after the campaign ended.
