To protect the precious bulk of Winston Churchill in wartime a special one-man pressure chamber was built for the personal plane which carried him many times across the Atlantic and to Casablanca, Moscow and Yalta. 

Churchill was warned by his doctors that it was dangerous for a man of his age and physical condition to fly above 8,000 feet. 

The solution was a pressure chamber complete with ash trays, telephone and an air-circulation system good enough to prevent smoke from the ubiquitous cigar from fogging the atmosphere.”

While many historians may not be aware of Canada’s role in this battle, they most likely have heard of the desperate fighting that engulfed the Gloustershire Regiment of the British Army further to the west, or even the 3rd Battalion Royal Australian Regiment that also retreated following the bitter fighting. Where these units were turned back, the Patricias held their ground and prevailed. Bjarnason compares the defense, and more importantly, the victory, to fabled stands: notably Custer at the Little Big Horn and the Spartans at Thermopylae. 

While not as widely known as the British part of the battle, the PPCLI held out against an onslaught of roughly 5000 Chinese “volunteers”, thwarting the attack at a loss of ten of their own.
