The Author's previous three books in this series - British Battalions on the Somme, 1916, British Regiments at Gallipoli andBritish Battalions in France and Belgium, 1914 have achieved all that they set out to do. On the historical side it is now agreed by a large number of grateful historians, researchers, museum curators, librarians etc. that for the first time they are able to establish quickly and conveniently what part each unit played in these important campaigns. It was also intended to provide family historians with a means of tracing the war service of their relatives. This again has been accomplished. British Battalions in France and Belgium, January- June, 1915 sets out with the same objectives in mind, on this occasion providing a unique account of the 291 infantry battalions of the British Army that served in France and Belgium from 1st January to the end of June, 1915. Over 500 volumes of war diaries and unit histories have been consulted, along with personal memoirs and diaries. Detailed records of movements, both in and out of battle areas and on a day-by-day basis, being covered in the same meticulous style as before.
