'Galloper' Jack Seely and his horse Warrior were one of the most remarkable teams in history. The man: a famed adventurer, Cabinet Minister and close friend of Winston Churchill, who led the Canadian Cavalry in a crucial charge that helped save the Allied cause in March 1918. The horse: a uniquely brave and talented thoroughbred which Seely bred on the Isle of Wight, took to France in August 1914 and was still riding on that fateful day towards the end of the war. The Canadians, all of whom held Warrior in great affection, referred to him during the conflict as "the horse the Germans can't kill.' Such was his fame that when he died in 1941 at the age of 32, the Times ran an obituary honouring the animal. In this film 'Galloper' Jack's grandson - award winning journalist and broadcaster Brough Scott - introduces a special profile on the legendary horse before taking to the saddle to explore the incredible past of both man and beast.
