Second relief of Lucknow: Twenty-four Victoria Crosses are awarded, the most in a single day.
The Siege of Lucknow was the prolonged defence of the British Residency within the city of Lucknow from rebel sepoys (Indian soldiers in the British East India Company's Army) during the Indian Rebellion of 1857. After two successive relief attempts had reached the city, the defenders and civilians were evacuated from the Residency, which was then abandoned.
