As lieutenant colonel, McLachlan commanded the 1st Battalion of the Cameron Highlanders in March 1913 and led it to France in the early stages of the World War I until September 1914, when he was wounded. He then commanded 8th Infantry Brigade from October 1915 to March 1916. He was awarded the Distinguished Service Order (June 1916) and mentioned in dispatches twice (January 1916 and June 1916). He served on the staff as a Brigadier General before being appointed as the first wartime military attaché to the United States; he arrived in the United States with his wife and two school girl daughters on 11 September 1917.

In-post, he was promoted to Major General. He was raised to a Companion of the Order of the Bath in 3 June 1918 and a Companion of the Order of St Michael and St George in June 1919. Upon relinquishing his post as military attaché, he reverted to his substantive rank of Colonel. He was awarded the United States Distinguished Service Medal in July 1919. He died on 7 November 1937.
