A 6-inch howitzer battery in action, Ypres, 1917

Photograph, World War One, Western Front (1914-1918), 1917.

The 6-inch 26 cwt howitzer entered service in late 1915. It was developed to replace the 6-inch 25 cwt and 6-inch 30 cwt howitzers which were outclassed by the latest German howitzers. The new gun's combination of firepower, range and mobility made it one of the war's best howitzers.
