Nafziger has included the text of some of the treaties binding his allies and an interesting account of the Prussian seperation and eventual capitulation during the retreat.
For anyone simulating or gaming the period, the book contains many hand drawn maps, which are very nice, with orders of battle and narrative accounts of the minor clashes and fringe battles.
I find the corps orders of battle indispensable for recreating the armies in miniature figurines. There is little or no uniform data, and some of the army descriptions (i.e. Berg, Saxon, Westphalian, etc.) are merely general descriptions, but Nafziger shows exacting and meticulous detail in providing »facts« in the order of battle and force compositions. He provides Corps, Division and Brigade breakdowns, including commanders name, unit names, number of battalions or squadrons, number and size of attached regimental guns, number of pioneer companies, nationality, etc. for the French and French allies. The same level of detail is provided for the Russian forces.
