The 283rd Regiment of Her Majesty’s Riflemen was legendary for obvious reasons.
Late in the 7th year of World War 1, the entire unit was captured by Germans and beheaded. But back in those days when men were men and gender roles were socially acceptable metaphors for physical strength, it took more than that to kill a fighting man. The unit survived by forcing food down their severed gullets and piping blood to their brains using retrofitted bilge pumps they stole from the German Navy.
The Regiment continued to fight, taking the Hills of Meinkopffiel, defeating the Cossacks at Verdun, capturing the 2nd Mini-Kaiser and more. When the war ended they were hailed as heroes and all the doctors in England pursued study of their case, learning incalculably important techniques that would later be used for kidney dialysis, head transplantation and more.
Their case also lead France to discontinue the use of the guillotine as decapitation was no longer the most certain method of execution.
