Volume Two tells the air story of the Gallipoli Campaign in 1915, and of the Western Front from the winter of 1914-15 to the end of the Battle of the Somme in November 1916, and of the naval operations in Home Waters to the end of 1916. It includes, also, the naval air operations from Dunkirk in 1915 and 1916 and the bombing operations from Luxeuil in the latter part of 1916. This volume incorporates the index of Volume 1 at the end of the book.

This official history of the part played in the Great War by the Royal Air Force is based chiefly on the records of the Air Ministry, collected and preserved by the historical section, supplemented by the contributions of many military and naval officers and civilian experts, as well as accounts of eyewitnesses. In all there are six volumes of text plus a supporting volume of appendices, published between 1922 and 1937.

With our 2020 reprint of the six text volumes of WAR IN THE AIR all bound in colour maps are present and correct where appropriate, an A4 printing size has been adopted to allow little or no reduction to this colour mapping, this larger format has also allowed a 20% increase in type sizing to the text pages that was previously rather small in the original editions.
