The Charge of the Light Brigade was a famous cavalry charge by British forces during the Battle of Balaclava in the Crimean War. The disastrously conceived offensive resulted in significant British losses.
The tragic event was immortalised by Alfred, Lord Tennyson, in his 1854 poem of the same name.
Extract from The Charge of the Light Brigade:
Cannon to right of them,
Cannon to left of them,
Cannon in front of them
Volley'd and thundered;
Storm'd at with shot and shell,
Boldly they rode and well,
Into the jaws of Death,
Into the mouth of Hell
Rode the six hundred.
