The phrase
die hard was first used during the
Battle of Albuera (1811) in the
Peninsular war. During the battle, Lieutenant-Colonel
William Inglis of the
57th (West Middlesex) Regiment of Foot was wounded by
canister shot. Despite his injuries, Inglis refused to retire from the battle but remained with the regimental
colours, encouraging his men with the words "Die hard 57th, die hard!" as they came under intense pressure from a French attack. The 'Die Hards' subsequently became the West Middlesex’s regimental nickname.
