In the Emperor's Service by Laurence Spring

Wallenstein's army 1625-34

This is the third 30 Years War book I have read by Laurence Spring and it is probably the best yet. Full analysis of the army from rations to quartering - coat colours and standards - arms and armour as well as tactics are all considered in detail. Special focus is on the famous pivotal battle of Lützen analysing the battle and its aftermath. Also the siege of Stralsund is examined. Well illustrated including many from the time in the form of engravings and colour plates by Mark Allen who also reproduces the flags and standards. If you have an interest in the 30 Years War you will probably enjoy this book
