The 4th Division in 1914-1918

The history of 4th Division

This Division, initially planned to be part of the original British Expeditionary Force, was at the last minute held back in England to counter any German landing. A decision was soon taken to despatch it to France and it arrived just in time to play a valuble part at Le Cateau. The 4th Division then remained on the Western Front throughout the war.
