History
Commercial Service
Silver State operated between Seattle, Washington, and the Far East with the Admiral Orient Line a subsidiary of the Pacific Mail Steamship Company. On 23 June 1922 the SS Silver State was renamed the SS President Jackson when the ship was purchased by the Dollar Line owned by Robert Dollar. In 1938 the SS President Jackson was transferred to the American President Lines.
Starting in 1937, the U.S. Navy studied converting the Dollar Line 535-foot (163 m) class ships to troop transports.[citation needed]
Commissioning
The SS President Jackson was acquired by the United States Navy in July 1940 and was renamed the Zeilin with the designation AP-9 after Brigadier General Jacob Zeilin (16 July 1806–18 November 1880) who was the first United States Marine Corps general.
The Todd Pacific Shipyards in Seattle, Washington, reconfigured the Zeilin as a troop transport. Commissioning occurred on 3 January 1942.
World War II
After a shakedown cruise and training along the west coast of the United States, the Zeilin left San Diego on 13 April 1942 transporting troops to Samoa for garrison duty and returning to San Diego on 17 June.
South Pacific Force and Guadalcanal
On 8 July 1942, Zeilin again departed San Diego and traveled via Pearl Harbor to Suva in Fiji. At Suva, Zeilin prepared for the invasion of the Solomon Islands. Zeilin was flagship of Transport Division Two[note 1] with the Amphibious Force, South Pacific Force under Rear Admiral Kelly Turner designated Task Force 62, re-designated from Task Group 61.2 under Operation Order 1—42 of 28 July issued by Vice Admiral Frank Jack Fletcher. Zeilin, with Betelgeuse part of Transport Division Two, was ordered to sail on or about 20 July 1942 for the South Pacific.
Early on the morning of 7 August 1942 Zeilin arrived off Guadalcanal with Task Force 62. On 8 August Marines from the 3rd Defense Battalion were landed by Zeilin on Tulagi, Gavutu, and Tanambogo. After completing disembarkation of the Marines, Zeilin traveled to Nouméa, New Caledonia.
For the next two months, Zeilin traveled a route between Nouméa; Espiritu Santo, New Hebrides, and Wellington, New Zealand. On 9 October, Zeilin departed Nouméa to carry troops and supplies to the Solomon Islands.
Arriving off Guadalcanal on 11 October, Zeilin began unloading at Lunga Point. On 13 October, Zeilin was attacked by a Japanese shore battery; but the ship did not receive any damage. Zeilin returned to Nouméa on 17 October and then proceeded to Espiritu Santo before returning to Lunga Point on 11 November.
At 09:00, the task group received a report that nine carrier bombers and 12 fighters were approaching from the northwest and would reach their vicinity at about 09:30. At about 09:20, Atlanta (CL-51) led the Zeilin and two other auxiliaries to the north, in column, with destroyers spaced in a circle around them. Fifteen minutes later, nine Japanese Aichi D3A "Val" dive bombers from the Japanese aircraft carrier Hiyō emerged from the clouds over Henderson Field.
At 09:40 the Zeilin opened fire. The Japanese airplanes dove on the Zeilin and released bombs at 1,200 feet (370 m). One aircraft was set on fire by Zeilin's guns There were three near misses registered on the ship; two on the port side - one about amidships, the other aft; and one on the starboard side at about frame 45 opposite No. 8 hatch, depth about 15–30 feet. The ship suffered severely from this bomb. The number 8 hold was flooded to the third deck; number 7 to the fourth deck. The starboard shaft was carried away. Zeilin took on approximately 2,000 tons of water. Examination by diver later disclosed cracked and ruptured hull plating as the cause of the flooding.
A second attack at 10:55 by 27 Mitsubishi G3M bombers was repulsed with anti-aircraft fire and fighter aircraft from Henderson Field.
Though damaged and listing, Zeilin carried casualties to Espiritu Santo and then sailed via Tutuila, Samoa to San Pedro, California. Zeilin arrived at the Terminal Island Naval Shipyard (later known as the Long Beach Naval Shipyard) on 22 December 1942 for repair. This repair work was completed in March 1943.
Aleutian Islands
On 17 April 1943, Zeilin left San Diego, California, for the Aleutian Islands. After a six-day stop in San Francisco, California, Zeilin continued on and arrived at Cold Bay, Alaska on 1 May. Cold Bay was the rendezvous point for the Attu Island invasion force. By 11 May the Zeilin was located off the south coast of Attu Island, at Massacre Bay. After the initial landings, Zeilin remained off Attu Island until 16 May. On 17 May, Zeilin stopped at Adak, Alaska, before leaving on 22 May and arriving at San Diego, California, on 31 May.
On 15 June 1943 Zeilin was designated as relief flagship, the battleship Pennsylvania being the flagship, for Commander Amphibious Force, Pacific Fleet. In June and July 1943, Zeilin operated along the west coast of the United States before returning to Adak on 5 August to participate in the invasion of Kiska, Alaska. Zeilin left Adak on 26 August, arriving at San Diego, California on 2 September.
Tarawa
The Zeilin traveled to Pearl Harbor, Hawaii, in mid-September 1943. After a five-day stay at Pearl Harbor Zeilin continued to Wellington, New Zealand, via Funafuti and Espiritu Santo arriving on 17 October. The ship remained at Wellington before departing on 1 November and proceeding to Efate in the Vanuatu where the attack force concentrated and practiced for the invasion of Tarawa.
On 13 November, Zeilin departed Efate and arrived off Betio on 19 November. Early the following morning, Marines from 2nd Battalion 2nd Marines were offloaded into landing craft from Zeilin for their assault. During the unloading operation Zeilin was under fire from Japanese shore guns. The ship did not sustain any damage from the attack. During this operation, Commander Thomas Benjamin Fitzpatrick was in command of the ship.

At Guadalcanal, the task group including the Zeilin conducted training exercises. The task group left Guadalcanal on 25 December arriving at Manus in the Admiralty Islands on 29 December.
On 2 January 1945, Zeilin left Manus and arrived off San Fabian, Luzon, in the Philippine Islands on 11 January. After offloading Zeilin departed on 12 January in convoy. The next morning, a single Japanese kamikaze aircraft attacked the convoy missing the amphibious command ship Mount Olympus (AGC-8) and striking Zeilin. The right wing of the Japanese aircraft struck cargo loading equipment next to the number 6 cargo hatch. The fuselage crashed into the starboard side of the housetop. Incendiary weapons carried by the aircraft exploded and started several fires on the ship. Topside damage to the Zeilin was extensive. The superstructure deck was destroyed, deck framing was damaged, and several staterooms were destroyed. The aircraft's engine pierced the deck, the outboard bulkhead and landed in a landing craft carried by the Zeilin. Seven crew members were killed, three crew members were declared missing, and 30 crew members were injured.
