Captain John Giffard took command of HMS Magnificent in February 1801 upon transfer from HMS Active. In April 1802, Giffard & the Magnificent helped to quell the mutiny by the 8th West India Regiment at Dominica. My 4th great grandfather, Lieut. Andrew Crawford served on the Magnificent between May & September 1802.
