- Temporary Captain

- Awarded on:
- August 31st, 1944
On the morning of 8th June 1944, this Officer was holding a position astride the Le Plein - Languemare Road with 1 Officer and 47 men. The Troop was attacked by a company of German Infantry which established itself in front of the position. Captain Alderson attacked with great determination leading the assault with a T.S.M.G. He himself accounted for a number of the enemy and his men were so inspired by his leadership that they carried on after he was wounded and cleared the entire wood which remains in our hands. Besides approximately 15 enemy killed there were 36 prisoners. Owing to Captain Alderson's skill and courage our own losses were no more than one killed and nine wounded. This success was largely due to Captain Alderson's fine leadership.
