Donald Walker MacDonald was born 6 July 1922 in Glasgow. He joined the Army as a boy soldier aged fifteen. In 1938, at the age of sixteen, he was sent out to Hong Kong where he served with the 2nd Battalion Royal Scots. The battalion had arrived in Hong Kong in January 1938 from India. I do not have a record of which company (Coy) he served in, but in 1975, he recalled in a press interview that he was based at the Shing Mun Redoubt. So we can assume he was with 'A' Coy commanded by Captain Cyril Jones.
'A' Coy consisted of three platoons, one of which was located in the redoubt, and the other two platoons were close to the redoubt. The Coy HQ was situated in an Artillery Observation Post (AOP) at the back of the redoubt.
