Summary of Operations 1/21/42 US West Coast: An unescorted transport returning to the US West Coast reports attempted attack by a Jap submarine identified as the I-19 southwest of San Francisco. An ASW escort had departed to meet the transport and provide an escort through the final approach into San Francisco – the escort did meet the transport following the sub attack and merged with it four hexes out from San Francisco. Current US ASW practice is to provide a temporary ASW screen to otherwise unescorted individual transports while they are moving through sea areas within 4-5 hexes of the US West Coast. This practice is done either as an attached escort to departing transport(s) until they are beyond the 4-5 hex range, or sending an ASW escort to merge with incoming transport(s) approaching the 4-5 hex range from the coast. Location of the Jap sub attack (hex 214,78) was eight hexes SW of San Francisco, outside the present ASW screening range from the US West Coast. At this point, it's believed the location of this particular Jap sub contact was more coincidental rather than a deliberate action by Pillager to station Jap sub patrols outside the 4-5 hex range. For now, my current practice for these ASW escorts hasn’t been employed to the extent or the frequency where Pillager could have established a pattern. Solomon Is: Japanese surface TF appeared at Tulagi – DD Ikazuchi hit mine laid in a defensive minefield laid by Australian CM Bungaree in 12/41. AAR follows. -------------------------------------------------------------------------------- TF 411 encounters mine field at Tulagi (114,137) Japanese Ships CA Myoko, Mine hits 1 DD Ikazuchi, Mine hits 1, on fire, heavy damage (confirmed sunk) -------------------------------------------------------------------------------- It appears from this action that Tulagi is Pillager’s likely next target for Japanese southward expansion in the SW Pacific area. Current position of Force N is within striking range of Tulagi with plans to engage Jap transports attempting an amphibious operation at Tulagi (which can reasonably be expected shortly). While the presence of Force N will not prevent an eventual Japanese capture of Tulagi, I intend to make the fall of Tulagi a bit expensive for Pillager if at all possible. New Guinea: Jap bombers (15 G3M Nell) continue attacking Port Moresby airfield. Five Jap bombers hit by flak, additional damage reported to airfield facilities. Current status of Port Moresby base – runway damage 32, airfield service damage 40, no port damage. Australia: Jap LBA bombers hit airfield facilities in Darwin. AAR follows. Moderate damage reported to airfield facilities at Darwin. -------------------------------------------------------------------------------- Morning Air attack on Darwin , at 76,124 Weather in hex: Clear sky Raid spotted at 15 NM, estimated altitude 8,000 feet. Estimated time to target is 5 minutes Japanese aircraft G4M1 Betty x 9 Allied aircraft no flights Japanese aircraft losses G4M1 Betty: 1 damaged Allied aircraft losses Hudson I: 1 destroyed on ground Wirraway: 1 destroyed on ground Allied ground losses: 4 casualties reported Squads: 0 destroyed, 0 disabled Non Combat: 0 destroyed, 0 disabled Engineers: 0 destroyed, 1 disabled Airbase hits 1 Airbase supply hits 5 Runway hits 9 Aircraft Attacking: 9 x G4M1 Betty bombing from 6000 feet Airfield Attack: 2 x 250 kg GP Bomb, 4 x 60 kg GP Bomb -------------------------------------------------------------------------------- Current status of Darwin base – airfield service damage 8, no runway or port damage. DEI: Dutch and USAAF level bombers launch strikes against Jap-controlled oil facilities at Balikpapan and Samarinda. AAR’s follow. -------------------------------------------------------------------------------- Morning Air attack on Balikpapan , at 64,97 Weather in hex: Severe storms Raid spotted at 40 NM, estimated altitude 9,000 feet. Estimated time to target is 15 minutes Japanese aircraft A6M2 Zero x 20 Ki-43-Ib Oscar x 3 Allied aircraft 139WH-3 x 27 No Japanese losses Allied aircraft losses 139WH-3: 10 destroyed, 8 damaged Oil hits 2 Aircraft Attacking: 2 x 139WH-3 bombing from 7000 feet * City Attack: 2 x 300 kg GP Bomb 1 x 139WH-3 bombing from 7000 feet * City Attack: 2 x 300 kg GP Bomb 5 x 139WH-3 bombing from 7000 feet * City Attack: 2 x 300 kg GP Bomb 2 x 139WH-3 bombing from 7000 feet * City Attack: 2 x 300 kg GP Bomb CAP engaged: Yamada Det S-1 with A6M2 Zero (7 airborne, 0 on standby, 0 scrambling) (7 plane(s) diverted to support CAP in hex.) 7 plane(s) intercepting now. Group patrol altitude is 10000 Raid is overhead 84th I.F.Chutai with Ki-43-Ib Oscar (1 airborne, 0 on standby, 0 scrambling) (3 plane(s) diverted to support CAP in hex.) 1 plane(s) intercepting now. 0 plane(s) not yet engaged, 0 being recalled, 2 out of immediate contact. Group patrol altitude is 15000 Time for all group planes to reach interception is 19 minutes Ryujo-1 with A6M2 Zero (1 airborne, 8 on standby, 0 scrambling) 1 plane(s) intercepting now. Group patrol altitude is 10000 , scrambling fighters to 10000. Time for all group planes to reach interception is 23 minutes Zuiho-1 with A6M2 Zero (0 airborne, 4 on standby, 0 scrambling) Group patrol altitude is 10000 , scrambling fighters to 10000. Time for all group planes to reach interception is 21 minutes -------------------------------------------------------------------------------- Morning Air attack on Balikpapan , at 64,97 Weather in hex: Severe storms Raid spotted at 40 NM, estimated altitude 11,000 feet. Estimated time to target is 15 minutes Japanese aircraft A6M2 Zero x 14 Ki-43-Ib Oscar x 1 Allied aircraft 139WH-3 x 2 No Japanese losses Allied aircraft losses 139WH-3: 1 destroyed CAP engaged: (same as preceding attack) -------------------------------------------------------------------------------- Morning Air attack on Samarinda , at 65,96 Weather in hex: Light rain Raid spotted at 17 NM, estimated altitude 8,000 feet. Estimated time to target is 4 minutes Allied aircraft B-17D Fortress x 5 Allied aircraft losses B-17D Fortress: 1 damaged Oil hits 2 Aircraft Attacking: 3 x B-17D Fortress bombing from 7000 feet * City Attack: 4 x 500 lb GP Bomb 2 x B-17D Fortress bombing from 7000 feet * City Attack: 4 x 500 lb GP Bomb CAP engaged: Yamada Det S-1 with A6M2 Zero (2 airborne, 0 on standby, 0 scrambling) 2 plane(s) intercepting now. Group patrol altitude is 10000 Raid is overhead Training flight from Yamada Det S-1 has been caught up in attack -------------------------------------------------------------------------------- Detected status of Samarinda base – oil production 79(22), 1 Japanese LCU, 39 Jap aircraft (19 fighters). This detected status indicates today’s B-17 raid produced a small amount of additional damage to oil facilities in Samarinda. Detected status of Balikpapan base – oil production 276(25), refinery 296(5), 4 Japanese LCU’s, undetermined number and type(s) of Jap aircraft. Also at least one detected Jap TF in Balikpapan. Plans are to continue employing Dutch level bombers in attacks against oil production facilities in Balikpapan as long as operational planes remain to do so. As these bombers will eventually be lost with the fall of the DEI, attacks on oil facilities are probably the (last and) most effective possible action for the Dutch bombers while they remain in existence. 43 Dutch 139-WH bombers (25 operational) remain with no available replacement planes. All available 139-WH planes in the replacement pool were used to rebuild Dutch bomber squadrons following strikes on oil facilities at Tarakan earlier in 1/42. Japanese ground forces capture Kolaka (SE Celebes near Kendari).
