One of the most used and most useful works of reference on the Great War ever published. In this marvellous volume is listed every cavalry and Yeomanry regiment, every battalion of every infantry regiment, Regular, Territorial or other - that existed during the Great War. In every case the location of the unit on 4 August 1914 is given, or the date and place of its formation if raised after the outbreak of war. Its initial disposition, subsequent moves, changes in subordination and final disposal or location on 11 November 1918 are all recorded. Thus, in a masterly and concise form, we have the war service record of 31 regular and 17 reserve cavalry regiments, 57 Yeomanry regiments and their second and third line counterparts and nearly 1,750 infantry battalions. Several appendices contain a mine of information; a table of the infantry regiments showing the number of the different types of battalions each had, regular, reserve, extra reserve, territorial, New Army, garrison etc.; how the New Army battalions were raised; the Training Reserve; list of infantry divisions; summary of battle honours, casualties and VCs of each infantry regiment. Finally, there is a good index.
This paper clearly shows the immediate relevancy of historical study to current events. One of the most common criticisms of the U.S. plan to invade Iraq in 2003 is that too few troops were used. The argument often fails to satisfy anyone for there is no standard against which to judge. A figure of 20 troops per 1000 of the local population is often mentioned as the standard, but as McGrath shows, that figure was arrived at with some questionable assumptions. By analyzing seven military operations from the last 100 years, he arrives at an average number of military forces per 1000 of the population that have been employed in what would generally be considered successful military campaigns. He also points out a variety of important factors affecting those numbers-from geography to local forces employed to supplement soldiers on the battlefield, to the use of contractors-among others.
