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  class ships to troop transports.

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 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  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,  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  emerged from the clouds over Henderson Field.

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.
