Most books on the colonisation of India view the subject in Eurocentric imperial terms, focusing on the ways in which European powers competed with each other on land and at sea and defeated Indian states on land, and viewing Indian states as having little interest in naval matters. This book, in contrast, reveals that there was substantial naval activity on the part of some Indian states and that this activity represented a serious threat to Britain's naval power. Considering the subject from an Indian point of view, the book discusses the naval activities of the Mahratta Confederacy and later those of Mysore under its energetic rulers Haidar Ali and his successor Tipu Sultan. It shows how these states chose deliberately to develop a naval strategy, seeing this as the most effective way of expelling the British from India; how their strategies learned from European maritime technology, successfully blending this with Indian technology; how their opposition to British naval power was at its most effective when they allied themselves with the other European naval powers in the region - France, Portugal and the Netherlands, whose maritime activities in the region are fully outlined and assessed; and how ultimately the Indian states' naval strategies failed.
