The Siege of Pondicherry (August – October 1748) was conducted by British forces against a French East India Company garrison under the command of Governor-General Joseph François Dupleix at the Indian port of Pondicherry. The British siege strategy, conducted with inexperience in siege tactics by Admiral Edward Boscawen, was lifted with the arrival of monsoon rains in October 1748. The siege was the last major action of the First Carnatic War, as the Indian theatre of the War of the Austrian Succession is sometimes known.
