Glassford's Task Force 5's light cruisers USS MARBLEHEAD (CL-12), USS BOISE (CL-47) and Cdr Paul H. Talbot's DesDiv 59's old destroyers USS PARROTT (DD-218), USS POPE (DD-225), USS JOHN D.

Storms protect the invasion force until it is almost to Balikpapan. At 1050, the convoy is attacked by three enemy aircraft, which are repulsed. At 1625, nine Dutch Martin Model 166 (B-10) bombers and four light bombers from Samarinda attack and hit transports TATSUGAMI and NANA MARUs. The latter is hit in No. 6 hold by a bomb, splinters from others that land to port alongside the same hold add to the fires raised. Navigation became impossible and over the following hours the flames take a firm grip. At 1730, ‘Abandon Ship’ is ordered. Finally, at 2100, after a huge explosion, NANA MARU sinks at 01-18S, 117-43E. TATSUGAMI MARU, only slightly damaged, continues on to Balikpapan. At 2045, Hirose's invasion convoy arrives and anchors off Balikpapan. At 2130, the transports begin disembarking troops.

At 0332, USS JOHN D. FORD scores gunfire hits on ASAHI MARU whose hospital ship status is obscured by the darkness. At 0335, USS PARROTT (DD-218) and USS PAUL JONES (DD-230) hit transport TATSUGAMI MARU with torpedoes in a deep fuel tank, the resultant flooding cause her to sink by the stern in Balikpapan Bay at 01-18 S, 117-04E, and four of her crew lose their lives.

USS POPE and USS PARROTT also sink the 2nd Base Force's patrol boat PB-37 with torpedoes and gunfire. At 0345, FORD sinks transport KURETAKE MARU with gunfire and torpedoes. Six crewmen and 272 troops are KIA. ASAHISAN MARU suffers damage from gunfire and torpedoes, but remains afloat. KUMAGAWA MARU suffers slight damage in the engagement. NITTEI MARU is not hit.
