Dutch Submarines

There are many naval details of WWII which we do not know about. Here are a few links for ships and Dutch submarines which were in Malayan waters. There is mention of Singapore, Borneo, and local cities and towns of Malaya and Siam - Kota Bharu, Patani, etc. There is mention of Pantai Timour in Bali, Indonesia. There is mention of Station Soerabaja (Surabaya). The Dutch submarines blog webmaster also seeks help from readers re people ID, event, location and date.

Exercised on K X, then K XI, K VIII, K XVIII, and K XII in August 1940.Was off West coast of Borneo when war with Japan started (7 Dec 1941). Sailed on board K XII to Singapore, loaded torpedoes from Submarine tender (probably tender Janssens) and went on patrol off the coast of Malaya.                   http://www.dutchsubmarines.com/men/crew/men_g_tigchelaar.htm
