The Portuguese had colonised several regions of India's west coast. They violated an agreement to give the Marathas a site on Salsette Island for a factory, and were intolerant of Hindus in their territory. In March 1737, the Peshwa dispatched a Maratha force (led by Chimaji) against them. Although the Marathas captured Ghodbunder Fort and nearly all of Vasai in the Battle of Vasai and gained control of Salsette on 16 May 1739 after a long siege, Nader Shah's invasion of India then diverted their attention from the Portuguese. The war trophies from Vasai included several Church bells which are found in many prominent Hindu temples in Maharashtra.
