The enemy, pressed upon by the detached column, changed their line of march towards the west, and General Roberts, still moving by forced marches, succeeded in coming up with them late on the evening of the 8th August. They were seen formed in great force near the village of Sanganeer--the number was estimated at 8000 men, two-thirds of whom were cavalry. The regiment at once advanced to the attack under a heavy fire from the artillery of the enemy, which, however, being directed too high, did no execution, while many of the rebels were killed and wounded by the rifles of the 83rd. Darkness, however, coming on, enabled the enemy to retire and withdraw the whole of their guns. The force had marched this day thirty miles, and bivouacked on the spot, having far outmarched their tents and baggage. Waiting one day to allow the column which had been detached from Tonk to join him, General Roberts’s force moved on the 10th August in pursuit of the enemy. This brigade had been reinforced by the junction of one troop of Bombay Horse Artillery, a squadron of the 8th Royal Irish Hussars, a squadron of Native Light Cavalry, 4 companies 72nd Highlanders, and a Sepoy Regiment of the Bombay army, as well as by a strong body of Belooch horsemen. A very persevering pursuit now took place on the track of the rebel army, the outpost picquets of which were surprised and cut to pieces on more than one occasion. At about 7 a.m. on the 14th August, the enemy were seen moving in heavy masses, of horse and foot, on the further bank of the Bunnass River, their line of movement being covered by their artillery, which was posted in a battery on the crest of a rising ground close to the village of Kottaria; only waiting to form and load, the force at once advanced towards the river, the 83rd Regiment leading in a double column of sub-divisions from its centre. The enemy’s guns opened with round and grape, and were instantly vigorously engaged by the British Horse Artillery, and the fire on both sides was for a time extremely heavy. The 83rd, forming line, crossed the river, meeting but little resistance, and the enemy, abandoning their guns, retired with precipitation. The cavalry charged amongst the retreating artillerymen and infantry, and the pursuit was continued for some miles, very great numbers of the rebels falling under their sabres, while the fugitives seeking shelter in the groves and copse-wood were destroyed by our infantry. In the evening the force returned and encamped near Kottaria, having sustained only the small loss of 22 killed and wounded, while fully 1000 of the rebels were left dead on the field, and 4 guns, with their ammunition, and many elephants and camels laden with stores, were captured. The enemy’s flight did not cease till they had crossed the Chumbul and entirely evacuated Rajpootana. The force returned northwards by easy marches, and the regiment reoccupied its former quarters in the camp at Nusseerabad on the 29th of August.
