Gough unexpectedly encountered Sher Singh's position near the Jhelum River on 13 January 1849. Sher Singh had cunningly concealed his army, and Gough was faced with the choice of withdrawing, or attacking when it was late in the day. Gough unhesitatingly took the latter course. The resulting Battle of Chillianwala was desperately fought. Gough's troops, attacking into thick scrub without effective artillery support, suffered heavy losses. Some units lost their colours (which was regarded as a disgrace) and part of one British cavalry regiment fled in panic, resulting in the loss of four guns, also reckoned a humiliation. Sher Singh's army was also hard hit, losing twelve of its own guns.
