Science and Civilisation in China Volume V Part 6 is the first of the three parts dealing with the arts of war in ancient and medieval China. (Part 7--on gunpowder and all aspects of explosive weapons--has already been published, while Part 8--on cavalry techniques and signaling--is still in preparation.) The present volume opens with an introduction on Chinese attitudes to warfare in general. Four major sections follow: on the making and use of simple bows; on the crossbow, the standard weapon of the Han armies, and its introduction to the Western world; on the pre-gunpowder forms of artillery, including the invention of the trebuchet; and on the art of siege warfare in which the Mohists were particularly interested. There is a good deal of material on siege-warfare available, and this final section is a substantial one, covering all aspects in detail.
