For the first month the regiment met with little opposition, and the camel-thorn, a wild bush, on the leaves of which camels feed, being found in great quantities, and large supplies of grain being taken, the condition of the camels, horses, and other baggage animals was much improved; the half-starved emaciated animals, which had marched from Jellalabad, quickly recovered their wonted vigour and efficiency. The warlike and turbulent Shinwaree tribes retired before Brigadier Monteath’s brigade, until they sheltered themselves in their strongholds, which were formed in a narrow valley, strengthened by many forts and stockaded enclosures, while the heights on either side were defended by numerous _sunghas_, or breastworks of large stones, which were so constructed as to enable them to dispute every inch of ground with an advancing force. The brigade having arrived, and encamped about two miles from this formidable position, a reconnoitring party was sent out, under the command of Captain Willes, of the THIRTY-FIRST regiment, to examine the strength of the enemy’s preparations, and determine his exact position. It was composed of two companies of the thirty-third Native Infantry, with a few Jezailchees, or Native Light Infantry, so named from the Jezail, or short rifle, with which they are armed. This party, having proceeded some four or five miles from the camp, was furiously attacked by a large force of Shinwarees, and suffered severely from their fire, which was very effective from the position they had taken up, and from which it required a very considerable force to drive them: nevertheless the object sought was fully obtained; the enemy’s position was correctly ascertained, together with every requisite information for the attack in force, after which the reconnoitring party returned to the camp, sustaining a smart action the whole way back. On the 26th of July Brigadier Monteath prepared to attack the enemy near _Mazeena_ with his whole force; and accordingly, leaving the camp standing under an efficient guard, he moved towards the position occupied by the Affghans, who were prepared, and nothing loth to meet him. Little time elapsed before the engagement was commenced by the THIRTY-FIRST regiment, seconded by the thirty-third and fifty-third Native Infantry, ascending the heights, and driving the Shinwarees from their breastworks, and along the ridges of the hills, while the tenth Light Cavalry, in the valley below, charged them whenever they showed front on level ground. The camp followers and pioneers had been furnished with combustibles to burn the forts, as the Shinwarees were driven out of them, which service was very efficiently performed. Meanwhile, on the heights, the enemy disputed every foot of ground until taken at the point of the bayonet, and Lieut. M‘Ilween, of the THIRTY-FIRST regiment, was killed while gallantly leading an attack of this kind against a vastly superior force.
