Edward Simpson's Career in the Civil War and Afterwards

Now at the USNA, Simpson was an instructor of naval gunnery and infantry tactics.  Prior to the Civil War, he was promoted to master, then to lieutenant.  In 1862, he was promoted to lieutenant-commander and in 1863, commanded the ironclad monitor USS Passaic in the South Atlantic Blockading Squadron.

As commander, he took part in the attacks on Fort Wagner in July and August 1863 and Fort Sumter in August and September 1863.

At some point, he was removed as the Passaic's commander and became the USS Isonomia's first commander.  Now, that ship was in no way the equal of the Passaic, so at some point I'd have to believe that something bad happened to Simpson's career.

Even so, he was promoted to commander in 1865 and captain in 1870.  The next two years were spent in Europe on special duty.  In 1877, he was detailed to the Brooklyn Navy Yard as captain, and in 1878, having been promoted to commodore he was commanding officer at the New London Naval Station.
