The wireless telegraphy Forward Spark 20 Watt B Mk II Rear Receiver was introduced in to service in 1917, along with a transmitter set (COM 3). It was liked for its compariative lightness,compactness and mobility. Used with a 60 feet long aerial for operating on 80 meteres, and a 50 feet long aerial for 65 metres, the general range of the set was from 2,000 to 3,000 yards. This made the set useful for communications between a battalion forward command post and a brigade
forward station. The set continued in use with the British Army until the end of the First World War, though some units began to receive improved equipment from the summer of 1918.
The Battle of Verdun (21 February-15 December 1916) became the longest battle in modern history. It was originally planned by the German Chief of General Staff, Erich von Falkenhayn to secure victory for Germany on the Western Front.
'Over The Top'. 1st Artists' Rifles at Marcoing, 30th December 1917, by John Nash.
Brothers Paul and John Nash were both commissioned as official war artists during the First World War - Paul from 1917 and John from 1918. Prior to becoming official war artists, both of the brothers had seen active service on the Western Front.
The trench warfare of the Western Front encouraged the development of new weaponry to break the stalemate. Poison gas was one such development. The first significant gas attack occurred at Ypres in April 1915, when the Germans released clouds of poisonous chlorine.
