Enlistment and War of 1812 Isaac Mayo entered service in the United States Navy at the age of 16 He received a Congressional Medal of Valor for his actions during the war.

Second Seminole war In 1840, Commander Isaac Mayo was assigned command of the sidewheel steam gunboat . He later commanded a squadron of gunboats during the campaign

United States Naval Academy In 1845, Captain Mayo sat on the 5 member board to determine the location of a permanent naval academy for the United States Navy. Knowing the advantages of the Fort Severn location, Mayo is credited with helping steer the board's decision to locate the academy there.

Mexican War In the 1840s as US General Scott advanced on Veracruz, he requested artillery support from Commodore Matthew C. Perry and the United States Naval forces nearby. On March 23, Captain Mayo was among those who came ashore with 8" guns from his ship. The naval battery deployed consisted of three 68-pound shell guns and three thirty-two pounders firing solid shot, and over 200 seamen and others attached to each in order to transport the massive weapons through knee-deep mud. Officers drew lots for the honor of commanding the sand-bagged battery and after the first day under the command of Captain Aulick, it passed to Captain Mayo While under Mayo's command on the 25th, the battery was able to silence the guns of Veracruz leading to its unconditional surrender on the 28th. of which Mayo was subsequently appointed governor.

In June, the 61-year-old officer was granted three months leave after two and a half years at sea on an 18th-century frigate, before returning to the examination of midshipmen at the academy.

Resignation and dismissal

Following the outbreak of hostilities between the Confederacy and the United States, Commodore Mayo was the oldest and longest-serving of the some 300 Navy officers who chose not to support the union, some 100 of whom resigned their commissions. Mayo wrote to President Abraham Lincoln:

"For more than half a century it has been the pride of my life to hold office under the Government of the United States. For twenty-five, I have engaged in active sea-service and have never seen my flag dishonored, or the American arms disgraced by defeat. It was the hope of my old age that I might die, as I had lived, an officer in the Navy of a free Government. This hope has been taken from me. In adopting the policy of coercion, you have denied to millions of freemen the rights of the Constitution and in its stead you have placed the will of a sectional Party. As one of the oldest soldiers of America, I protest—in the name of humanity—against this "war against brethren!" I cannot fight against the Constitution while pretending to fight for it. You will therefore oblige me by accepting my resignation."

Lincoln, while granting other such requests, ordered Mayo's dismissal from the Navy effective May 18, 1861. However, Commodore Mayo had died May 10, 1861, of a gunshot wound at Gresham house.
