Germany had plenty of problems of it's own with fuel supplies. It was blockaded in the Atlantic ocean. Japan had it's own sources for oil from
Sumatra and Brunei and supply ships of it's own supplying the Kuril islands.
If you read anything in depth about the relationship between Germany and Japan, each country paid the other for exchanges of good and these exchanges
were recorded and were the subject of diplomatic signals which were read by the Allies. A German fuel dump would not be established on a Pacific
Island without good reason. Indeed it would logically only be established there for German aircraft.
For years critics have denied a German air link to Japan and have said show us the proof. Now I provide some proof and the critics say ... Oh there
must be some other reason.
Matua (Matsuwa) island had a rocky coast with an elevated terrace. These German drums did not just end up there by chance.
That might be a valid explanation for a German fuel drum in Yokohama where the odd German Merchant raider sheltered earlier in the war, but this was
1943 when most German Merchant Raiders had already departed the Pacific. Remember these drums were manufactured 1943.
In addition, a captured German POW revealed under British interrogation in April 1944 that during 1943 the ultra long range Messerschmitt Me-264 flew
special communications flights to Japan from Petsamo in Northern Finland. Well here is a logical destination for such flights. It's runway was
intentionally plumbed with geothermal steam to keep the runway snow free year round. Russian sources mention two runways one 1570m x 35m and the other
2000 metres. The Me-264 was known to require a very long runway and these runways were well beyond the needs of Japanese aircraft using the airfield.
From late 1943 onwards Matua was bombed incessantly by the American 11th Air force in Alaska using B-25 Mitchells, B-24 Liberators and even on
occasion B-17 bombers. By mid 1944 it was the subject of very intensive daily armed photo reconnaissance by flights of three B-24s escorted by P-38
lightnings. Why daily reconnaissance?
What was so important there?
When the Soviets took it over they discovered a labyrinth of deep tunnels and cavities all across this 11 kilometre long island.
