Sergeant William Henry Delisle Alfin won the Military Medal for bravery during the Third Battle of Ypres. William was the son of Charles Alfin and his wife of North Luffenham and was born at Ketton on 10 October 1889. He joined the 1st Battalion Middlesex Regiment on 13 March 1916, and went to the Western Front on 15 July. A year later he won the MM beating off an enemy attack: "South of Polygon Wood, on the 25 and 26 September 1917, this NCO performed very useful work by the skilful disposition of his Lewis gun team during the enemy's attacks, remaining cool throughout, and accounting for many of the enemy. His bravery, cheerfulness and calmness were very inspiring throughout the action." He also took part in the Battle of Arras, and was killed by a shell on 26 October 1918, near High Wood on the Somme, less than three weeks before the Armistice. He was 29 and is buried at Awoingt British Cemetery, grave II.B.22, and remembered on North Luffenham's war memorial.
