Carnatic wars

In 1751, there was an ongoing scuffle between Muhammed Ali Khan Wallajah, (who was the son of the previous Nawab of Arcot Anwaruddin Muhammed Khan hence the rightful claimant) and Chanda Sahib his relative and a pretender, for the throne of Arcot. The former sought the help of British and the latter the French. Chanda Sahib initially succeeded and became the Nawab, forcing Muhammed Ali to escape to the rock-fort in Tiruchirapalli. Chanda Sahib followed and with the help of the French, besieged Trichy. Muhammed Ali and the English force supporting him were in a grim position. Ensign Robert Clive, (who had earlier joined the East India Company as a writer) with a small English force of 300 soldiers made a diversionary attack on Arcot to draw away Chanda Sahib's army from Trichy. Chanda Sahib dispatched a 10,000 strong force under his son Raza Sahib to retake Arcot. Raza Sahib was aided by the Nellore Army and Yusuf Khan as a Subedar must have been in this force. At Arcot, and later at Kaveripakkam, Chanda Sahib’s son was badly defeated by Robert Clive, and it was now Chanda Sahib's turn to escape to Tanjore where he was killed by Mankoji, a Tanjorean general. The English quickly installed Muhammed Ali as the Nawab of Arcot and most of Chanda Sahib's native forces defected to the English.
