In 1740 the War of the Austrian Succession broke out in Europe. Great Britain was drawn into the war in 1744, opposed to France and its allies. The trading companies of both countries maintained cordial relations in India while their parent countries were bitter enemies on the European continent. Dodwell writes, "Such were the friendly relations between the English and the French that the French sent their goods and merchandise from Pondicherry to Madras for safe custody." Although French company officials were ordered to avoid conflict, British officials were not, and were furthermore notified that a Royal Navy fleet was en route. After the British initially captured a few French merchant ships, the French called for backup from as far afield as Isle de France (now Mauritius), beginning an escalation in naval forces in the area. In July 1746 French commander La Bourdonnais and British Admiral Edward Peyton fought an indecisive action off Negapatam, after which the British fleet withdrew to Bengal. On 21 September 1746, the French captured the British outpost at Madras. La Bourdonnais had promised to return Madras to the British, but Dupleix withdrew that promise, and wanted to give Madras to Anwar-ud-din after the capture. The Nawab then sent a 10,000-man army to take Madras from the French but was decisively repulsed by a small French force in the Battle of Adyar. The French then made several attempts to capture the British Fort St. David at Cuddalore, but the timely arrivals of reinforcements halted these and eventually turned the tables on the French. British Admiral Edward Boscawen besieged Pondicherry in the later months of 1748, but lifted the siege with the advent of the monsoon rains in October.
