In the beginning of September a detachment of troops under Colonel Oldham, of which the THIRTY-SIXTH formed part, marched from Errode to join Colonel Floyd at _Sattimungulum_, which place was reached in three days. Colonel Floyd’s entire force now consisted of His Majesty’s Nineteenth light dragoons and sixteen troops of Native cavalry, His Majesty’s THIRTY-SIXTH regiment and five battalions of Native infantry, eleven guns, and a due proportion of artillerymen and officers. Detachments of cavalry were sent almost every day to scour the country towards the Gudzelhetty Pass, and they generally brought in a few of the enemy’s horse, belonging to Syde Saib’s party, stationed at the foot of the Ghauts, who were much distressed for provisions and forage, his people having been constantly obliged to cross the Boovany, in order to procure grain in the different villages, in which places they were generally taken prisoners; their horses were very small and bad. A deposit of grain and provisions was in the meantime formed in this frontier station for the use of the army under Major-General Medows, which was destined to ascend to Mysore by the Gudzelhetty Pass early in October. On the 11th and 12th of September it was reported in camp that Tippoo, in person, had descended the Gudzelhetty Pass with a large army of cavalry and infantry, with several pieces of artillery. On the morning of the 12th of September Tippoo’s army, estimated at about thirty thousand cavalry, infantry, and artillery, descended the Gudzelhetty Pass, and crossed the Boovany river at daybreak of the following morning. A reconnoitring party of British cavalry, under Major Child, encountered the enemy’s advance guard of cavalry on the 13th, and compelled it to recross the river. On the 12th at night orders had been given to Major Darley to march with his regiment of Native cavalry towards the Pass early in the morning, to support Major Child, and he had not proceeded three miles, when he perceived a large body of cavalry advancing, and was immediately charged by them; being so much pressed on all sides, he was obliged to take post and keep off the enemy while his ammunition lasted, which was nearly expended, when Colonel Floyd, with the remainder of the cavalry, came to his support, to whom he had sent information on first perceiving the enemy; this reinforcement fortunately arrived just in time, as Major Darley’s regiment was in a very dangerous situation. Colonel Floyd, unperceived by Tippoo’s forces, charged them in flank with three troops of the Nineteenth light dragoons, supported by the remainder of the regiment, entirely routed them, and pursued them to the river; it was supposed that the enemy had nearly five hundred killed on the ground, and a great number drowned in endeavouring to recross the river, which was fordable in very few places, while those were deep and dangerous.
