That same day, the Japanese attack the forts of Wusong and Jabei on the Whangpoa (Huangpu) River. The next day, heavy fighting breaks out as the Imperial Japanese Army (IJA) relieves the surrounded SNLF contingent. The IJN brings its heavy naval guns to bear on the Chinese. The fighting results in a heavy loss of civilian lives and property and causes the Chinese to unify. The Japanese are unable to capture Shanghai.
By the end of the month, IJA troops called in to assist the SNLF number 50,000 men under General Shirakawa. His troops encircle the Chinese 19th Route Army and force a Cease-Fire. The Japanese establish a puppet government and make the last Emperor of China, Henry Pu Yi, the Emperor of Manchukuo (former Manchuria).

2 July 1937:
Lae, New Guinea. World famous aviatrix Amelia Earhart and her navigator Fred Noonan take off in a twin-engine Lockheed 10E "Electra" on a 2,556 mile leg to Howland Island as part of their attempt to fly around-the-world, but their plane disappears.
Tokyo. Emperor Hirohito's (Showa) younger brother LtCdr (later Captain) Prince Nobuhito Takamatsu (52), a staff officer at the Naval General Staff, receives the news of Earhart? disappearance. He persuades the Chief of the NGS, Fleet Admiral, Prince, Hiroyasu Fushimi to order KAMOI to search for Earhart. 
Mandates. KAMOI receives the order, but it does not contain any information upon which Captain Kozaka can base his search. A few hours later, the order is canceled. No trace of Earhart's plane or crew is ever found.*
7 July 1937: The Marco Polo Bridge (The First "China") Incident:
Lugouqiao, China. Japanese troops are on night maneuvers at the bridge. They fire blank cartridges. Chinese troops fire back, but do not cause injuries.

14 August 1937: "Bloody Saturday":
Shanghai. Flagship USS AUGUSTA (CA-31), carrying the CINC, U.S. Asiatic Fleet, Admiral Harry E. Yarnell (USNA ·7)(former CO of USS SARATOGA, CV-3), arrives after battling a typhoon enroute from Tsingtao. Enroute to her buoy in the Whangpoa River, she passes Japanese light cruisers, destroyers and other ships who render passing honors to USS AUGUSTA? embarked admiral.
That day, following a series of land battles, the Chinese Air Force (CAF) under their acting operational CO, retired Captain (later MajGen) Claire L. Chennault, launches aircraft to attack the IJN flagship IZUMO and the Japanese fleet. The CAF mistakenly bombs the British cruiser HMS CUMBERLAND, but their bombs fall wide. Two bombs also fall close alongside USS AUGUSTA, but no one is killed. The CAF accidentally drops bombs into Shanghai city, killing more than 1700 civilians and wounding 1800 others. A Type 90 scout floatplane from IZUMO attacks the CAF formations and shoots down a fighter.
20 August 1937:
Shanghai. KAMOI is on station with Vice Admiral (later Admiral) Hasegawa Kiyoshi's (31) (former CO of NAGATO) Third Fleet. Northrop 2-E "Gamma" light bombers of the CAF's 14th Squadron flown by foreign mercenaries bomb Japanese positions in the International Settlement. The bombs fall short and cause extensive damage and heavy loss of life among neutrals in the settlement. One CAF plane drops two bombs that explode off the USS AUGUSTA's starboard side killing one seaman and wounding 17 others.
12 October 1937:
Shanghai. Two of KAMOI? Type 95 Kawanishi E8N2 two-seat float biplanes take off on a reconnaissance mission of the capital of Nanking. The Chinese air raid warning net reports their approach. A flight of Curtiss "Hawk III" biplanes intercept the IJN floatplanes over Chiang-yin. In the ensuing melee, a Hawk III collides with an IJN floatplane. The E8N2 crashes in flames, but the Hawk pilot survives a forced landing. The other E8N2 is shot up and lands on the Yangtze (now Changjiang) River. The Hawks strafe and sink it. Both E8N2 crews are KIA.
12 December 1937: The "China Incident."
Yangtze River. About 1327, LtCdr (later Cdr) James J. Hughes' (USNA ·5) river gunboat USS PANAY (PR-5) is attacked by IJN aircraft while escorting three Socony Vacuum Oil Company barges MEI PING, MEI SHIA and MEI AN. The attack continues until 1554 when USS PANAY sinks. Three men are killed and 43 sailors and five passengers are wounded. Two of the three oil barges are also bombed and destroyed.
Tokyo. American Ambassador Joseph C. Grew immediately lodges a formal protest. The Japanese government accepts responsibility, but claims the attack was unintentional.
Washington, DC. The militarily unprepared United States government is anxious to avoid war. The Roosevelt Administration accepts the "mistake" theory, together with an indemnity of $2.2 million paid in April 1938, and the incident is officially settled.
KAMOI launches a flight of E8N2 floatplanes to attack Canton (Guangzhou). One E8N2 shoots down a Chinese scout plane over the city. The next day, four E8N2s encounter a lone, but powerful, Gloster Gladiator of the Chinese Air Force being flown by a British pilot. In a 10-minute dog fight, the Englishman holds off his attackers. He escapes after scoring many hits on the Daves.

The United States Asiatic Fleet, British Royal Navy and French Navy respond by sending naval units and detachments from all three nations·ships to oppose IJN troops ashore. Eventually, the Japanese back down.
25 August 1938:
Captain (later Rear Admiral) Matsuda Chiaki (44) (former XO of ABUKUMA) assumes command. Captain Iwabuchi is reassigned to the Naval General Staff.
KAMOI operates on the Yangtze River against the Chinese. The Yangtze is so deep and wide that ocean-going vessels and large cruisers can steam all the way up to Hankow.
12-25 October 1938: The Fall of Canton:
The Japanese launch a major offensive in southern China. KAMOI, seaplane tender NOTORO and carriers KAGA, SORYU and RYUJO participate.

KAMOI is in the eastern Marshall Islands, principally Kwajalein, Roi, Wotje and Jaluit? Emidj. KAMOI's mission is to find suitable locations for future seaplane/flying boat operations in the event of war and to provide service for the Yokohama Kokutai on overflights in the Gilbert Islands and other areas.

Salajar Strait, Celebes. About 0550, LtCdr (later Cdr) Walter T. Griffith's (USNA '34) USS BOWFIN (SS-284) with COMSUBSOWESPAC Rear Admiral (later Vice Admiral) Ralph W. Christie (USNA '35) aboard for a "familiarization" war patrol, spots KAMOI and an escort. Griffith tracks KAMOI all day, but is forced to dive five times by her seaplane air cover.
At about 2100, running on the surface, Griffith fires six bow torpedoes at KAMOI in a radar attack, but she zigs and they all miss. The escort's crew does not see BOWFIN, but starts dropping depth charges. Griffith moves off to reload.
At 2200, BOWFIN makes another surface attack with six torpedoes. Two torpedoes hit KAMOI below the bridge. Griffith closes the range on the surface, but suddenly KAMOI opens fire at BOWFIN with her two 4-inch deck guns and machine-guns. Griffith zigzags away at high speed, but remains on the surface. At 2245, he fires two stern torpedoes at KAMOI, but they both miss.
At 2329, Griffith fires two more stern torpedoes at KAMOI and both hit. KAMOI belches black smoke and is down by the bow, but still afloat at 04-08S, 117-50E. Griffith fires another stern torpedo, but misses. BOWFIN again closes the range on the surface, but KAMOI's crew sees the submarine and opens fire. Griffith outruns KAMOI's guns, then turns back. At 2348, he fires his last bow torpedo that hits KAMOI between the bow and the bridge. KAMOI is beached to keep her from sinking.

1 February 1944:
Arrives at Seletar Naval Base, Singapore for major repairs by the No. 101 Repair Unit.
15 April 1944:
Singapore. Japan's need for tankers to transport oil from the East Indies to the homeland and her far-flung island conquests far exceed her need for seaplane tenders, so KAMOI's seaplane handling equipment is removed and she is rerated an oiler.
16 April 1944:
Singapore. Target ship HAKACHI ties up on starboard side of KAMOI, presumably to bunker. Light cruiser KITAKAMI is already lying alongside.

Stevenson fires three torpedoes by periscope at a tanker and claims one hit, but actually achieves no results. At 1530, LtCdr William C. Thompson's (USNA '35) USS CABRILLA (SS-288) torpedoes HOKUREI MARU and YAMAMIZU MARU No. 2. YAMAMIZU MARU No. 2 sinks with the loss of 56 of her crew. Only two survivors were rescued.
