The Battle of the Ice Mound, February 7, 1815
by Robert G. Stewart
Even though war was declared in 1812, Marylanders did not seem to become alarmed until 1813 when the British blockaded the Chesapeake and the Delaware Bays. The Maryland's 48th Regiment of Militia of Dorchester County was formed.
This is the Dorchester County, Maryland Roster for the 48th Regiment of the 12th Brigade.
The H.M.S. Dauntless was anchored off James' Island. What alerted the local people was that sailors from a Tender to the British ship had come ashore on February 5th, 1815 and stole supplies from one of the farms. They had reason to believe they would be back for more. The Militia was ordered to readiness. Keep in mind there was ice in the Chesapeake Bay at the time. On February 7th, 1815 at the Ice-Mound, a group of men under the command of Joseph Stewart made their way over the ice to the ship. There was a battle. After about two hours of engagement, these Maryland men captured the British Tender. The British prisoners were taken across the Ice and marched ashore. These prisoners were sent to Easton, MD. The British prisoners were later returned to England.
Joseph Stewart and his men petitioned both houses of Congress on February 24, 1815 for their prize in capturing the British Tender. On December 14, 1818, each man involved received $42.90 in prize money.
