He served in Decatur and Petrel in the Mexican War, and gave distinguished service in the Civil War in command of Fannie, Pinola, Florida, Keystone State and Metacomet and as fleet captain in the North Atlantic Blockading Squadron. In Pinola, assisted by Itaska, he broke the chain barrier across the Mississippi to make possible the passage upriver of Flag Officer D. G. Farragut’s squadron, and the capture of New Orleans.

Rear Admiral Crosby retired in March 1882, and died in Washington, D.C., 15 June 1899.
