In the early morning of June 8, 1916, in the southwest Pacific Ocean, about 100 nautical miles east of the Solomon Islands, 16 warships flying between the Dragon Flag, the Taiji Flag, and the Rising Sun Flag were dividing into three columns and cautiously heading south with a Z-shaped anti-submarine route.

The sky was faintly bright, the whistle sounded, and a group of colorful signal flags rushed up to the high mast of the flagship "Jinpeng," and the fleet began to change formations, and warships of all sizes were either left or right, or accelerated or slowed down or rotated, dazzling but orderly, and I saw that the three columns gradually merged into one, like an abstract giant wheel that replaced the line with points, and unfolded impressively on the sea within a radius of three or four kilometers.

On the bridge of the fleet aircraft carrier "Jinpeng", the commander of the mobile unit under the Guadalcanal Raiders of the East Asian Coalition Army, General Dongfang Gao, twisted a telegram in his hand, and his seemingly calm gaze wandered through the porthole, wandering between the clear blue sea and sky that had just been washed by the storm.

The East Asian Alliance's strategy for the Solomon Islands began in March, when Operation I entered the Indian Ocean communication line through operation, and the main force of the Combined Fleet and most of the sea capacity were invested in the Indian Ocean, and the southeast theater of operations, which was responsible for the attack, could only be supplemented with limited troops and capacity.

In order to prevent Tsarist Russia, which was short of military supplies, from receiving arms and machinery from the European and American allies more effectively through this line of communication, the base camp of the Chinese army urgently set up the 1st Combined Air Force of the Army and Navy to be stationed in Turkey, in an attempt to block the communication of the strait by breaking the battle between the sea and the air. The 101st Mixed Aviation Wing of the Army, which was assigned to the theater of operations at the beginning of the year, was forcibly transferred.

When the first phase of Operation SF, Operation Solomon and Fiji Islands Raiders, began, the naval forces attached to the Southeast Front Theater were divided into the Southeast Front Fleet and the 6th Air Force, which:

The Southeastern Front Fleet is mainly responsible for escorting convoy regiments, guarding important places, and breaking diplomatic relations in theater transport ships, with four old armored cruisers, seven old light cruisers, 18 old destroyers, and the 1st Mobile Fleet as the main strike force, which is responsible for annihilating the main force of the enemy's surface fleet, and the backbone force is 4 super-dreadnought high-speed battleships, 1 battle cruiser, 8 light cruisers, and the 2nd Mobile Fleet as the landing support force, which is responsible for directly escorting and supporting the landing fleet in carrying out amphibious landing operations. The backbone force consists of 4 old battleships, 3 old armored cruisers, 4 light cruisers, 2 seaplane carriers, and the 6th Air Force, which is the base aviation unit with its headquarters in Rabaul, and is responsible for the task of providing coastal aviation support, with a total of 152 squadron combat aircraft and 12 aircraft directly under the squadron, totaling 164 aircraft, including: 3 land reconnaissance aircraft, 63 land attack aircraft, 36 land fighters, 36 water fighters, and 24 water reconnaissance aircraft.

Under the escort of the 2nd Mobile Fleet, nearly 13,800 troops of the Army Raiders based on the 125th Reserve Infantry Division landed on Bougainville Island, and without fierce fighting, the whole island was pacified within a week, and the 1st Mobile Fleet of the defending army was annihilated cruising in the Solomon Sea to provide long-range cover.

The Chinese army immediately rushed to repair the airfield in Buin, in the south of Bougainville Island, and at the same time set up a seaplane anchorage on Shortland Island, across the sea from the south of the island, and stationed most of the 6th Air Force.

The 1st Mobile Fleet was towed out of the Southeast Theater of Operations and transferred to the Aleutian Islands via Hawaii to cover the counterattack of the Japanese North Sea Front Fleet (2 old armored cruisers, 4 old light cruisers, and a total of 33,000 men from each of the 9th Division on Kodiak Island and the Kenai Peninsula in the Gulf of Alaska, and landed smoothly without almost no resistance. After several weeks of searching, 149 survivors of the nearly 10,000 defenders of the original Kodiak Island were rescued who escaped the enemy's search and hid in the jungle and successfully survived the severe winter of minus 10 degrees Celsius, while less than 1,000 of the 3,000 defenders of the Kenai Peninsula who were not attacked returned to the team. After nearly six months of deprivation of supplies and freezing temperatures, almost all of the survivors were skeletons, more than half of them were unconscious when they were rescued, and a large number of broken human bones were found in the area where they were hiding, apparently cut and even boiled with sharp weapons......

During this period, the 2nd Mobile Fleet served as long-range cover and the main force of the Southeast Front Fleet provided direct support, and 14,500 Army Raiders based on the 128th Reserve Infantry Division launched a landing operation on the coast of New Georgia, 230 kilometers southeast of Bougainville Island.

In mid-May, after covering the withdrawal of Japanese counteroffensive forces from Kodiak Island and the Kenai Peninsula and their transfer to the Aleutian Islands, the ships of the 1st Mobile Fleet were briefly overhauled at the Yokosuka and Kure military ports in Japan and the Pusan military port in North Korea, and regrouped at the port of Kaohsiung in Taiwan in late May to join up with the 2nd Air Force and other units deployed by the Combined Fleet, and finally returned to Rabaul on 2 June.

On 3 June, the base camp re-ordered the operations of the Southeast Front and issued an order for the second phase of the SF operation: to build an airfield on the coast of Guadalcanal, 250 kilometers southeast of New Georgia, and to establish a seaplane base in Tulagi, north of Kuah Island.

On 5 June, the Kuah Island Raider Force was organized under the unified command of Marshal Zhang Yiye, commander of the Southeast Theater Command, and was under the following commands: Advance Troops, Mobile Units, Main Forces, Support Units, Tulagi Raider Troops, Kuah Island Raider Troops, Munda Base Air Force (New Georgia Island), and Bouin Base Air Force (Bougainville Island).
