HMS Janissary

HMS Janissary or Janizary was a gun-boat that served in the Royal Navy's Egyptian campaign (8 March – 2 September 1801). She appears in the records only in connection with the campaign and her origins before 1800 or service after 1801 are lost. Her name honours the Janissaries, a body of Ottoman troops.

On 2 March, while under the command of Lieutenant John Whilley, Janissary, together with the cutter HMS Cruelle (1800) and the gun-vessel HMS Dangereuse (1799), protected the left flank during the landing of troops in Aboukir Bay. The cutter HMS Entreprenante (1799), schooner HMS Malta (1800 schooner), and the gun-vessel Negresse covered the right flank. Janissary's officers and crew therefore qualified for the clasp "Egypt" to the Naval General Service Medal that the Admiralty authorised in 1850 to all surviving claimants.
