Edwin Ward Moore (July 15, 1810 – October 5, 1865), was a United States Navy officer who also served as commodore (1839–1843) and commander in chief of the navy of the Republic of Texas.
Moore was born in Alexandria, Virginia. His grandfather and uncle had served in the American Revolution. Moore was a classmate of Robert E. Lee at the Alexandria Academy.
Moore entered the United States Navy as a midshipman in 1825 at the age of fifteen.
His first assignment came when he was posted to the USS Hornet, followed by stints on the Fairchild and the Delaware. He saw active service on the Atlantic Coast and the Mediterranean Sea. In 1830, Moore was stationed at the Gosport Navy Yard and five years later was commissioned a lieutenant and assigned to the sloop-of-war Boston on July 1, 1836. While serving on the Boston, Moore saved the ship from sinking when it encountered heavy seas in a hurricane.
In September 1836, the Boston, captured the Texas privateer Terrible off the coast of New Orleans. The Texas ship was sent to Pensacola, Florida, on piracy charges. It is believed this contact with the Texans prompted Moore to re-evaluate his military career. Promotion within the U.S. Navy at this time was a slow process as many of the officers who served in the War of 1812 still held rank above Moore
In 1839, Moore was accused of recruiting officers and up to eighty sailors from the Boston to join him in enlisting with the Republic of Texas Navy. Moore's cousin, Alexander Moore, confirmed this rumor to Commodore Charles Ridgley who forwarded the charges to the Secretary of the Navy. On July 8, 1839, Moore resigned from the U.S. Navy to become commander of the Republic of Texas Navy.
