Beginning with the Harappan age, Indian history is crowded with wars fought on its land. These wars led to the birth and decline of many a kingdoms and empires. As armies and weapons were basic instruments of war, various tactics related to their use also came to be perfected over the centuries. This work is prefaced by a general survey of the wars fought in ancient India, whose accounts are available, to serve as a backdrop to the study. The rise and fall of the kingdoms covered in this study provide substantial evidence of wars fought galore in ancient India. With time new strategies of war such as circle theory, six means, four measures, etc., came to be developed. Advanced modes of combat were devised and new methods related to the use of various weapons were perfected. But far more important were the strategical and tactical concepts perfected by the Indians over the centuries. The Mahabharata and works like the Arthasastra, the Kamandakiy Nitisara and the Sukraniti contain graphic descriptions of war tactics as these evolved over the centuries. It is hoped that this study will inspire researchers to delve deeper into this little explored field of study.
