The War of the Austrian Succession in Europe spilled onto the Coromandel coast. The French took Madras and, at the Adyar, showed that a small European-drilled force could rout an Indian army. The war ended in a draw.

Result

The French took Madras and beat the Nawab’s army, but the peace of Aix-la-Chapelle in 1748 gave Madras back to the English.

01Madras and the Adyar

When Britain and France went to war in 1744, the English and French companies in India at first hoped to keep the peace. A British squadron began seizing French ships, and in 1746 La Bourdonnais came from Mauritius with a fleet and took Madras in September. The Nawab of Arcot, Anwaruddin Khan, demanded the town for himself and sent his son Mahfuz Khan to take it. At the Adyar river in October and November 1746 the French routed his army.

02Stalemate

Dupleix kept Madras against the bargain La Bourdonnais had made to ransom it, and the two Frenchmen quarrelled bitterly. The French then tried several times to take the small English post at Fort St David near Cuddalore, and failed. In 1748 a large British fleet under Admiral Boscawen besieged Pondicherry, and failed in turn. News of the peace of Aix-la-Chapelle arrived, and Madras was handed back to the English in 1749 in exchange for Louisbourg in North America.

Why it matters

The war changed nothing on the map, but the Adyar taught Dupleix and the English alike that their drilled troops could decide Indian successions; the Second Carnatic War followed at once.
