Served as seaman on board the USS Pensacola in the attack on Forts Jackson and St. Philip, 24 April 1862. Carrying out his duties throughout the din and roar of the battle, Lyons never once erred in his brave performance. Lashed outside of that vessel, on the port-sheet chain, with the lead in hand to lead the ship past the forts, Lyons never flinched, although under a heavy fire from the forts and rebel gunboats.
