The Battle of Chinsurah (also known as the Battle of Biderra) takes place near Chinsurah, India on November 25, 1759 during the Seven Years' War between a force of British troops mainly of the British East India Company and a force of the Dutch East India Company which had been invited by the Nawab of Bengal Mir Jafar to help him eject the British and establish themselves as the leading commercial company in Bengal.
Despite Britain and the Dutch Republic not formally being at war, the Dutch advance up the Hooghly River.
They meet a mixed force of British and local troops at Chinsura, just outside Calcutta.
The British, under Colonel Francis Forde, defeat the Dutch, forcing them to withdraw.
The British engage and defeat the ships the Dutch used to deliver the troops in a separate naval battle on November 24.
