This victory reinforced the idea in the Confederate War Department that Flag Officer Foote's Union Mississippi River Squadron at the north end of the Mississippi was the greatest threat to the Confederacy. The Battle of Fort Henry, the Battle of Fort Donelson, and the Battle of Shiloh lent a lot of credibility to this idea. As a result, the mosquito fleet and "Ivy" were ordered to the upper Mississippi and took part in the Battle of Island Number 10. Island Number 10 was a defeat for the Confederate forces involved. The mosquito fleet could not match and after these ships successfully ran the Confederate batteries, and it was forced to retreat.
