A recent purchase of mine... Military Operations France and Belgium 1914, volume 1 & 11 text, volume 1 & 2 maps. Military Operations France and Belgium 1915, volume 1 & 11 text, volume 1 & 11 maps. Strictly speaking - not from WW1, the first book being published in 1922. All volumes were formerly housed in the Royal Engineers library. The volumes are highly detailed accounts of the battles. There are approximately 1800 pages and about 80 large fold-out maps covering from August 1914 to the end of 1915. my aim is to eventually have the full set - about 26 volumes.
