In 1791, Nujuff Cooli Khan again broke into rebellion. Ismail Beg was despatched to arrest him; but when the latter reached Rewari, where the rebel chief had set up his head-quarters, he learned that Nujuff was dead. However, the widow of Nujuff Cooli, a woman akin to Begum Somroo, of a masculine spirit, possessing, moreover, considerable military abilities, took command of deceased's forces. Knowing that Ismaeel Beg was courageous, talented, and ambitious, she proposed an alliance, which he accepted; and throwing himself into the town of Canoor, defended it against the Mahrattas. The Begum displayed the utmost courage throughout the siege, and invariably joined in all the sorties made by the garrison. Unfortunately, this brave woman was slain in a skirmish by a cannon-ball, and her death broke up the rebel camp. It was resolved by the garrison to deliver up Ismaeel Beg to the Mahrattas; but he was beforehand with them, and surrendered the town. General Thomas, in his zeal for the Begum Somroo's interests, raised up enemies for himself in the principal French and German officers. They took occasion to poison the Begum's mind against him by foul accusations; and in 1792 he was compelled to withdraw to Anopsheer, one of the frontier stations of the British army. Early in 1793, he took service under Appakandarow, a Mahratta chieftain. Le Vaissaux, or Levasso, a German adventurer, commanding the Begum's artillery, had always been Thomas's deadly foe, and was the leading man in driving him away. He possessed great military talents, and had rendered considerable services to his mistress; but he was a man of haughty, overbearing mien, and hated by all his brother-officers. Great was their indignation, though they were scarcely surprised, when the Begum, disregarding their remonstrances, and the advice, the all but commands, of the Emperor, surrendered her hand and heart to the German artilleryman, in 1793. Begum Somroo, instigated by her husband, now determined to crush poor Thomas; and at the head of four battalions of foot, four hundred horse, and twenty pieces of cannon, she marched towards Jyjur, where he was stationed. But the Mahratta chiefs, who had long been jealous of her influence over Shah Aulem, stirred up a mutiny amongst the troops left in Serdhauna, and compelled her to return thither with all speed. The officers, to give a sanction to their proceedings, offered the jaghire to Zuffer Yab Khan, son of Somroo by a former wife. He was a young man of worthless and turbulent character; since his father's death he had lived in Delhi, receiving a handsome allowance from his step-mother.
