[1] In Captain Hara Tameichi's famous and important book "Japanese Destroyer Captain" the sequence of events for the Battle of Java Sea are unfortunately either recalled incorrectly, or confused in translation. The date/times of the various anti-submarine actions, and the escorting of Op Ten Noort, as related in his book are considerably in error when compared to the real-time messages and War Diaries of involved units including Amatsukaze's own rather detailed TROM and Action Report. The sequence as set down in this TROM accords with the primary evidence. If Hara's narrative is read with this corrected chronology in mind, it still matches very closely to the events. Part of the confusion was due to the fact that Amatsukaze was involved with Op Ten Noort twice; first on 28 February, then escorting it to Borneo on 1-2 March.- (Tully)

[2] Captain Hara's memoir describes two actions against enemy submarines, the text (in English at least) implies the first was at 0340 March 2, and the second around 2030 "the following night" which would be 3 March. However, the second section of Desdiv 16 (Amatsukaze and Hatsukaze) in fact made three anti-submarine attacks in a three day period. It is not a wonder some confusion has crept in. The first was at 0110 1 March and is likely USS Perch (SS-176) as many assume. However, the second undersea encounter at 2225 that same day's evening may be the Dutch K-10. The third and last one - Hara's second narrated -- but actually the pair's third anti-sub action at 2030 3 March cannot be Perch. She had been sunk at 0700 that same morning. Also, the submarine was not already crippled and even attacked with torpedoes. It must have been Dutch but its identity is unclear. - (Tully)

[3] It is of interest to note that the corrected timeline shows that the survivor patch Amatsukaze passed through while convoying the hospital ship that Hara described in his book was that of Exeter and Encounter and they indeed were mostly rescued. Hara's recall of visiting them later aboard Op Ten Noort on 6 March is correct for this is when Amatsukaze arrived in Bandjarmasin for the second time to replenish. Op Ten Noort did not depart for Makassar till 8 March.- (Tully)

[4] Editorial Note I - USS Redfin's patrol report reveals the submarine was stalking the convoy near dusk on the surface when the Amatsukaze was sighted overtaking steadily from astern. Suddenly the Japanese destroyer lit off all boilers, and commenced a charge. Redfin had been sighted, and a hot pursuit ensued. At 1949 (sub was using H-time, here adjusted to JST) the Amatsukaze opened fire. Cornered Redfin retaliated with four stern tubes; one of which struck the port bow at 1952 setting off the forward magazine and producing a fireball that caused the sub to believe all its torpedoes had struck and demolished the destroyer. - (Tully)

[5] Editorial Note II - Spectacular photographs taken during Amatsukaze's final action reveal the character of her transformation. Her hull had been cut off at the former location of No.1 TT mount, and a temporary bridge and snub-nosed bow fitted there. Her No.2 stack became her only stack, and was just abaft the temporary bridge. Perhaps not surprisingly, in this case No.2 5-inch turret was not removed, and she retained both aft turrets. From No.2 stack aft, Amatsukaze thus remained a normal looking Kagero-class destroyer.- (Tully)

[6] Editorial Note III - Hi88J indeed suffered heavily. Of the original composition of seven marus - Sarawak, Kaiko, Asokawa, Honan, Araosan, Tencho, Saigon Maru -- and seven escorts - No.134 (Flag), Nos. 18, 26, 84, 130,134, Manju, and Amatsukaze; four marus and three kaibokan were crippled or sunk by the time they arrived at Hainan Island on 30 March. - (Tully)

[7] These B-25s were from the 500th and 498th Bomb Squadrons of 345th Bombardment Group. With the 501st and 499 Squadrons they formed an anti-shipping strike launched that day. The 501st and 499th sank CD-1 and CD-134 only twenty minutes prior to the attack on Amatsukaze by the other two squadrons. - (Tully)

[8] Of interest Lt. Morita was appointed to command of the Sijiao Island garrison, China Theater Fleet and remained there till after the war. - (Tully)
