Meanwhile, despite these successes and Lawrence's brilliant action at Bahoor French influence was, on the whole, decidedly on the gaining hand. Within six weeks of Bahoor, thanks to the indefatigable intrigues of Dupleix, both Mysoreans and Mahrattas had alienated themselves from the English and openly attached themselves to the French cause. Dalton had from the first been troubled by conspiracies and other mischievous designs of the Mysoreans in Seringham, which compelled him to take precautions in Trichinopoly as elaborate as though he were in presence of an enemy. Dupleix, seeing that affairs were going as he wished, promised to send some Europeans to help the Mysoreans in Seringham; and the Mysoreans, thus encouraged, moved a step further forward and suborned the Mahrattas to cut off supplies from the city. It was now useless for the authorities at Madras longer to pretend to treat the Mysoreans otherwise than as enemies. Accordingly, early in January 1753 Dalton attempted a surprise of their camp in Seringham, which though at first successful was eventually repulsed with the serious loss of seventy Europeans and three hundred of the best Sepoys. Thus the struggle for Trichinopoly, the darling object of Dupleix's ambition, was reopened, and reopened by a reverse to the British. Dalton, undismayed though fully alive to the significance of his failure, now turned all his attention to the defence of the city. [Sidenote: March.] His situation indeed was most critical. Even before his sortie he had discovered that but three weeks' supplies were left to him, and had urged Lawrence to march to his relief; and now not only were his communications with the north severed by the hostile occupation of Seringham, but a force of eight thousand men had entrenched itself at a place called Fakir's Tope, four miles to south-west of the city, to intercept all supplies from the south. Meanwhile, to divert the British from Trichinopoly, Dupleix had skilfully engaged Lawrence in a campaign of petty, harassing operations on the river Pennar; while the Mahrattas scoured every part of the Carnatic from the Paliar to the Coleroon, insulting even the fortifications of Fort St. David. Lawrence in vain strove to bring the French to action. They were following the tactics of Saxe in the Low Countries, always present and therefore always a danger, but always entrenched to the teeth against attack. Finally, after an unsuccessful attempt to storm their entrenchments, Lawrence resolved to adopt the course so often urged by Ligonier in Flanders, to carry the war into some other quarter. So far his operations had proved a failure, and the reputation of the British had accordingly waned paler than ever in the eyes of the native princes. He was still hesitating as to the choice of a new theatre of operations when his mind was made up for him by the receipt of Dalton's letters from Trichinopoly.
