The Sinai and Palestine Campaigns took place in the Middle Eastern Theatre of World War I. A series of battles were fought between British Empire, German Empire and Ottoman Empire forces from 26 January 1915 to 31 October 1918, when the Armistice of Mudros was signed between the Ottoman Empire and the Entente Powers. This book is an account of the Palestine campaign, "illustrated from the experiences of one who was present" by Major H. O. Lock of the Dorsetshire Regiment and was first published in 1919.
