This encounter was precipitated by a violent raid on Fort Williams a year earlier.  One commander, fresh off his victory at Arcot, secretly negotiated with the other commander's uncle, Mir Jaffar, in order to secure an advantage. When an attack on a French settlement near Murshidabad provoked one side to march into battle, the other had already set up his defenses in a mango grove on the Hooghli River.  Though badly outmanned, a monsoon rain and the judicious use of a tarp to keep the powder dry turned the charge of Siraj-ud-Dawlah's forces into a rout for the British.  FTP identify this battle fought on June 23, 1757, a victory by Robert Clive that secured colonial domination of India.
