Very soon after the events at Meerut, rebellion erupted in the state of Awadh (also known as Oudh, in modern-day Uttar Pradesh), which had been annexed barely a year before. The British Commissioner resident at Lucknow, Sir Henry Lawrence, had enough time to fortify his position inside the Residency compound. The defenders, including loyal sepoys, numbered some 1700 men. The rebels' assaults were unsuccessful, so they began a barrage of artillery and musket fire into the compound. Lawrence was one of the first casualties. He was succeeded by John Eardley Inglis. The rebels tried to breach the walls with explosives and bypass them via tunnels that led to underground close combat. After 90 days of siege, the defenders were reduced to 300 loyal sepoys, 350 British soldiers and 550 non-combatants.
