HNLMS K XVII appears to be a Dutch submarine sunk by a mine in Gulf of Siam in December 1941.

I'm not sure how that is relevant to Pearl Harbor several thousand miles away.

We already know that Japanese troops landed in Northern Malaya a few hours before the Peal Harbor strike. We also know it took hours for word to reach the British command in Singapore, who then had to send it to the War Office in London, which then had to tell Churchill, by which time Peal Harbor was already being bombed. Communications in 1941 were primitive.

If your not sure how that is relevant do a little research into it.
