John P. Davidson 
Haig [PDF ebook] 
Master of the Field

A distinguished soldier who had served in South Africa, the Author was selected to be Haigs Director of Operations in 1915, a key position he held until the end of the War. This book concentrates on the dramatic events of 1917 and 1918 and covers Third Ypres, the German onslaught (Kaiserschlacht), and the victorious 100 Days. We learn of the parlous state of the French Army, their loss of morale and the widespread mutinies.Tavish Davidsons viewpoint on the conduct of operations was unique and we learn of the factors at play in Haigs HQ. The German U-Boat fleets ports became a high priority as losses of shipping mounted, threatening the whole war effort. We get the German perspective Passchendaele 1917 was even more costly for them than the Allies.Davidson comes down wholeheartedly on Haigs side but this should not be a surprise as Haig was revered by his officers and men. It only became fashionable to pillory him much later.This is an important addition to the bibliography of the Great War.
