Kingston's Fort Henry-- Part 2: Involved in the Royal George Fight

From Wikipedia.

At the beginning of the War of 1812, local militia erected a blockhouse and battery at Point Henry, Kingston.  On November 10, 1812, the battery was involved in turning away several American warships attacking the Provincial Marine sloop Royal George as it was taking refuge in Kingston Harbor.

Because of this, it became evident that a stronger fortification was needed and the militia and regular army began a more permanent fortification in 1813.  It was one of several defensive structures built in and around Kingston during the war.

In 1820, Fort Henry consisted of earth and stone ramparts, demi-bastions, redans, ditches, magazines, barracks, signal towers and support batteries.

It was determined that a much strong fortification was needed.
