30 January 1942. Balikpapan, Borneo.
<snip>
The loss of much of the Sakaguchi Detachment in that failure had meant that to regain the initiative and take Balikpapan, the Ito Detachment was off the coast of Borneo ready to try again. Along with the close escort of one Cruiser, fifteen destroyers, a variety of patrol boats and sub-chasers, protecting the eleven transports, the Distant Cover Force had sailed south from the Celebes Sea into the Makassar Strait, much closer to the invasion fleet than they had been previously.
With the increased air reconnaissance being done by the Dutch and Australians, the Japanese fleet had been spotted and tailed while the Dutch, British and Americans scrambled to get as many submarines into position to attrit the Japanese navy as possible.
In the event six submarines managed to get into shooting positions before the invasion took place. The four Dutch boats claimed five ships sunk between them, the two T Class RN submarines claimed another three, and damage to another two. The USN submarines reported two ships sunk, but again problems with torpedoes. The USAAF put together a B17 strike but was unable to claim any hits on the ships, two bombers were lost to Japanese naval fighters from the carriers. Attempts by the Dutch Naval Aviation, Air Force and the RAAF to interfere was slightly more successful, a few ships were damaged, but at a high cost to the attacking crews and aircraft.
