It was, therefore, believed at the Mound piquet that ample warning would be given of any enemy coming from the direction of the Trunk Road, so that the approach of some horsemen dressed like the men of the 9th Irregulars attracted little notice.
Stillman and Hills were breakfasting together, when a sowar from the Native officers' party rode up and reported that a body of the enemy's Cavalry were in sight.

Hills told the man to gallop to Head-Quarters with the report, and to warn Tombs as he passed his tent.

Hills and Stillman then mounted their men, neither of them having the remotest idea that the news of the enemy's advance had been purposely delayed until there was not time to turn out the troops.

They imagined that the sowar was acting in good faith and had given them sufficient notice, and while Hills moved his guns towards the position from which he could command the Trunk Road, Stillman proceeded to the top of the Mound in order to get a better view of the ground over which the enemy were said to be advancing.

The troop of the Carabineers was thus left by itself to receive the first rush of the rebel Cavalry; it was composed of young soldiers, some of them quite untrained, who turned and broke.
The moment Hills saw the enemy he shouted, 'Action front!' and, in the hope of giving his men time to load and fire a round of grape, he gallantly charged the head of the column single-handed, cut down the leading man, struck the second, and then was then ridden down himself.
It had been raining heavily, so Hills wore his cloak; which probably saved his life, for it was cut through in many places, as were his jacket and even his shirt.
As soon as the body of the enemy had passed on, Hills, extricating himself from his horse, got up and searched for his sword, which he had lost in the melee.
