The "Light Brigade" refers to a British cavalry unit that played a significant role during the Crimean War, particularly in the Battle of Balaclava on October 25, 1854. This brigade is best known for its charge against Russian artillery, which was part of a miscommunication in military orders. The charge resulted in heavy casualties but demonstrated the bravery and valor of the soldiers involved. The event is famously commemorated in the poem "The Charge of the Light Brigade" by Alfred Lord Tennyson, which highlights the courage and sacrifice of the troops. Despite the disastrous outcome, the charge has become a symbol of heroism in military history.
