In Truth of the War Conspiracy of 1861 Johnstone explains how Lincoln and his co-conspirators used deceit, half truths, lies and violation of international law to promote their war conspiracy. Johnstone wrote his book in 1917 using documentation which was not available when the post war Confederates, such as Davis, Stephens, Semmes and Pollard, wrote their histories of the conflict. Johnstone adds even more documentation and explanation to how Lincoln managed to initiate his war of aggression against the people of the South who merely wanted to be "left alone" to live under a government ordered on the consent of the governed.

This is a hybrid between an old fashioned type of Indian Army unit history and the more informative style which later replaced it. The text is still rooted firmly in extracts from Regimental records and official reports, but the authors have expanded upon these with their own linking narrative. Although brief, the result is readable and informative.Appendixes, Honours and awards, list of former COs, other officers, notes on Battle Honours, badges and insignia complete this history.Regimental Great War Battle Honours are: Loos, France and Flanders 1915, Helles, Krithia, Gallipoli 1915, Suez Canal, Egypt 1915-17, Gaza, Megiddo, Sharon, Nablus, Palestine 1917-18, Defence of Kut al Amara, Kut al Amara 1917, Baghdad, Mesopotamia 1915-18, Aden, E Africa 1914-17, NW Frontier India 1915 '16-17 Afghanistan 1919
