About one-half of all Lend Lease shipment from the United States to the Soviet Union via the north Pacific route. Japanese during the war respecting their neutrality treaty with the Soviets and NOT interfering with these voyages.
The famous Murmansk/Arctic route accounting for about one-quarter of all Lend Lease sent to the Soviet, forty or so convoy, each convoy carrying enough war-stuff and munitions to equip an army of about 50,000 men.
That Arctic route through the Bering Strait open perhaps only for about two months of the year. The Black Sea via the Dardanelles and Bosporus route a favorite idea of Churchill but of relatively minor importance in comparison to the whole.
THAT AMOUNT OF LEND-LEASE WAR-STUFF AND MUNITIONS AS SENT TO THE SOVIET UNION DURING WW2 STUPENDOUS. NOT EVEN COUNTING ADDITIONAL LEND-LEASE AS PROVIDED TO ALLIED FORCES WHOM EVER THEY MIGHT HAVE BEEN!!
