Siege of Lucknow or the First War of Indian Independence.
Sir Colin Campbell easily crossed the nearly dry Charbagh Canal and advanced on the Secundrabagh, which housed most of the rebels. After its walls were breached by covering artillery fire, the 93rd Highlanders, part of the 53rd Regiment of Foot, the 4th Punjab Infantry, and various other detachments stormed it. It was a horrific defeat for the rebels. According to Campbell, some 2,000 rebels died. Later that day, Campbell’s forces also stormed the Shah Najaf mosque, only a few hundred yards from the British defenders of the Chuttur Munzil.
