Holkar sent back a long list of demands, which were impossible to satisfy; and also addressed a letter to General--now Sir Arthur--Wellesley, threatening to overrun the whole country, unless some of the districts in the Deccan were ceded to him and, after sending off this letter, he began raiding the territory of Jaipore.

Colonel Murray was therefore sent to aid the rajah, and to march in the direction of Holkar's capital; while Lord Lake marched westward, until he neared Jaipore.
On the 15th of May a detachment captured the strong fort of Rampoora, the sole fortress which Holkar possessed north of the Chumbul river; and Holkar immediately fell back.

The heat being now intense, the general left Colonel Monson, with five battalions of Sepoys and three thousand irregular horse, sent by Rajpoot allies, and returned to Agra, losing numbers of his men on the march, by sunstroke.
Harry had been left with Colonel Monson.

The latter, intending to cooperate with Colonel Murray, entered Holkar's territory and, on the way, captured a strong hill fort.

He afterwards advanced fifty miles beyond the range of mountains that formed the frontier.
On the 7th of July he heard that Holkar was advancing, with his whole army, to meet him.
