Gough had intended to attack the Sikh army in its entrenchments at Sobraon as soon as Smith's division rejoined from Ludhiana, but Hardinge forced him to wait until a heavy artillery train had arrived. At last, he moved forward early on 10 February. The start of the battle was delayed by heavy fog, but as it lifted, 35 British heavy guns and howitzers opened fire. The Sikh cannon replied. The bombardment went on for two hours without much effect on the Sikh defences. Gough was told that his heavy guns were running short of ammunition and is alleged to have replied, "Thank God! Then I'll be at them with the bayonet."
