Herbert Tuxis Armstrong DFM was born in 1920, at Canoe Lake, Ontario (ON), which is about 50 miles east of Huntsville in Algonquin Park, the son of Dr. W. Allan & Mrs. Armstrong of Ottawa ON. Before enlisting in the RCAF he was taking the Arts & Science course at Queen's University, Kingston ON.

After training in Canada, he went overseas in 1942. In 1943, he was a Flight Sergeant-Pilot on a Halifax bomber involved in ten hour patrols westerly from a base in the UK, which was engaged in the hazardous work of convoy patrol and sinking German submarines. He was awarded the Distinguished Flying Medal (DFM) for his skill and bravery on the occasion when the aircraft he was piloting, searched the North Sea for, and located a dinghy in which the nine man crew of an American bomber were marooned.

Although only fifty miles from the enemy coast exposed to attacks by enemy fighters, he directed an allied ship to the dinghy and remained with the dinghy for five hours. The American crew was rescued successfully. He completed one tour of operations with the City of Vancouver Squadron and also one tour with an RAF Squadron.

He was raised to the rank of Flying Officer and prior to returning to Canada, his aircraft was engaged in delivering guns to the French Forces in the interior before the 1944 invasion of Normandy. He ended his overseas service by instructing a Canadian Heavy Conversion Unit.

On July 24, 1945, he was married to Marjorie Parkinson of Scarborough, England, before returning to Canada.
