Another, larger, force under General Colin Campbell, the new Commander-in-Chief, India, gathered in Cawnpore to make a second relief of Lucknow. While he led his main force to Lucknow, Campbell left a detachment of about 1,500 men under Brigadier Charles Ash Windham to hold Cawnpore, the vital bridge of boats across the Ganges, and the entrenchment constructed to protect it. Windham had a reputation for bravery gained in the Crimean War, and was nicknamed "Redan" Windham, after a Russian fortification at Sevastopol.
