On 10 February 1846, on the swampy east bank of the Sutlej river at Sobraon, the First Anglo-Sikh War reached its bloody end. The Khalsa army of the Sikh Empire had thrown a fortified bridgehead across the river, linked to Punjab by a single pontoon bridge of boats. Facing them stood Sir Hugh Gough's East India Company army, backed by heavy siege guns. What the ordinary Sikh soldier did not know was that his own senior commanders, Tej Singh and Lal Singh, were already in secret contact with the British and had no intention of winning. Into that betrayal stepped Sardar Sham Singh Attariwala, a white-bearded veteran of Maharaja Ranjit Singh's court, nearly sixty years old. He bathed, dressed in plain white, vowed before his men to conquer the field or die on it, and when the position began to collapse he led charge after charge until he fell, his body pierced by musket balls. The Khalsa was shattered, the pontoon bridge broke, thousands drowned trying to cross, and within weeks the Treaty of Lahore began Britain's grip on Punjab.
