Gale, Anthony.
Fourth Commandant of the Marine Corps. Born in Ireland on Sept 17, 1782, as a young Marine officer serving in the Ganges he had been struck by a Navy junior officer whom he "called out" and shot. The action was received as honorable by then Commandant William Burrows. Following the death of Commandant Wharton in 1818 the position was filled in an acting capacity by Adjutant and Inspector, Brevet Major Samuel Miller and then by Brevet Major Archibald Henderson. Gale's short tenure as Lieutenant Colonel Commandant was punctuated with the dislike of the Secretary of the Navy who charged him in a court martial. The specifications included, "being intoxicated in common dram shops and other places of low repute." He pleaded not guilty by reason of temporary insanity but was found guilty and sentenced to dismissal from the service. He died about 1843 and his place of burial is unknown. He also remains the only Commandant for whom no likeness exists.

We have fought in every clime and place, where we could take a gun
From the snows of far off northern lands, and in sunny tropic scenes
You will find us always on the job, The United States Marines

Here's health to you and to our Corps, which we are proud to serve

If the Army and the Navy, ever looked on heaven's scenes
They would find the streets are guarded by, The United States Marines
