The Forty-Sixth Division was a military formation of the British Army during the early 20th century. It was primarily active during World War I and was known for its involvement in various battles on the Western Front. The division was composed of several infantry brigades and supported by artillery and other units. After the war, the Forty-Sixth Division was disbanded, but its legacy continued through the Territorial Army, which aimed to maintain a reserve of trained soldiers. The division's history reflects the broader changes in military organization and strategy during and after the war.
