It was evidently the object of the enemy to prevent the junction of the Umballa division with the Ferozepore field force, to cut off the latter division, and to capture the fort and magazines of Ferozepore, before the Umballa division could arrive at the scene of action. The enemy hoped also to have a rich booty in the plunder of the large town of Ferozepore. The Sikhs knew and calculated the distance the Umballa troops had to march before they could reach the vicinity of Ferozepore, one hundred and fifty miles, and the nature of the country through which they had to march; but they did not calculate on the energy, patient endurance of hardships, and privation, which the British soldier would cheerfully undergo, when he knew, that his brave and heroic Commander-in-Chief was leading him in person against the foe, who had dared to invade the British possessions. On the 10th of December the THIRTY-FIRST received the order to march, and the morning of the 12th saw the regiment leave Umballa, mustering 30 officers and 844 men. After long and harassing marches of twenty-five to thirty miles a day, the severe nature of which it is impossible to describe, the regiment arrived at the village of _Moodkee_ about two o’clock in the afternoon of the 18th of December, having on that day performed a march of not less than twenty-five miles: some idea may be formed of the sufferings which the men endured from fatigue on this eventful day, when it is known that at the last halt, about two miles from Moodkee, scarcely _fifty_ men were left with the colours; and for miles to the rear they might be seen staggering forward through the soft sand in an exhausted state from want of water and rest. The soldiers were in the act of pitching their tents, and had eaten nothing, when the alarm was given that the enemy was close upon them in force. The THIRTY-FIRST rushed to arms, and forming the right of the first brigade of the first division, under Major-General Sir Henry Smith, formed in quarter-distance column, left in front, advanced two or three miles, deployed on the grenadier company, and so continued the line formed by the regiments on their right.
