As the cold weather began in November, substantial contingents from the East India Company's armies at last took the field. A contingent from the Bombay Army (administered separately from the Bengal Army) had been ordered to reinforce Whish and besiege Multan. This force was delayed by a petty squabble over seniority and could arrive only when its first commander (who was senior to Whish and refused to serve under him) was replaced by a more junior officer. Whish's army was supplied and reinforced by sea and river transport up the rivers Indus and Chenab. Whish renewed the siege of Multan on 27 December, with 17,000 men and 64 guns. After a heavy bombardment the city was stormed on 2 January, 1849. On 22 January, Mulraj surrendered the citadel. He was imprisoned for the remainder of his life. The ending of the siege allowed Whish, with large numbers of heavy guns, to reinforce the army under Sir Hugh Gough.
