Described by its author as 'a useful little treatise' this book, simply and clearly written, and intended for study by 'soldiers and subalterns' is an exposition of the tactics to be used defending outposts. Opportunely published on the eve of the Crimean War and Indian Mutiny - which both featured the tactics it expounds in sieges and storming fortifications, - this timely treatise is also beautifully illustrated with drawings and diagrams.
