A number of victories on the high seas with the defeat of the Graf Spee, in the desert and Far East have shown that Great Britain still has the reserves and military forces to fight a global war.

For Great Britain to survive, the sea lanes have to be kept open, with precious cargoes of troops, war materiél and food being brought by merchant shipping.

British naval and air forces are deployed to far off ports and stations such as Gibraltar, Malta, Singapore and Hong Kong to protect the vital sea lanes.

Southern Rhodesia, South Africa, New Zealand and Australia mobilize for a war that has not yet reached their borders, but commit to proving Great Britain with supplies.

Canada has also become an integral part of the fight against the Axis, building up its defences, keeping the Atlantic sea routes free for shipping and providing food for the beleaguered Great Britain.

Armament and munitions factories also receive contracts to produce the weapons of war, with warships, tanks and aircraft constantly rolling off production lines to meet the requirements of a greatly increased military force.

The incorporation of President Roosevelt's Four Freedoms Speech established the rationale for the United States becoming more involved in the Allied war effort.
