The SS Samoa was a 1,997-ton cargo ship that was able to escape an attack off the coast of California in the early days of World War II. The Samoa was built under a United States Shipping Board (USSB) contract in 1918 as the SS Muerthe, but was launched as the USS Lake Pepin, named after Lake Pepin, by the McDougall Duluth Shipbuilding Company of Duluth, Minnesota measured at 3,600 tons deadweight. She had a triple expansion engine steam engine with 1250hp, a 251feet length, 43.5feet beam, a draft of 17inchesftNaNinchesin (ftin), a top speed of 9.25kn. The vessel had a crew of 52, with the hull # 9 and O.N.ID # 21699. The USS Lake Pepin (ID # 4215) was owned and operated by the United States Navy, commissioned at Montreal, Quebec, Canada on 4 September 1918. For World War I she was fitted with one 3"/50 caliber gun. The Navy put her in Naval Overseas Transportation Service as a coal carrier traveling between the United Kingdom and France as a United States Navy Temporary auxiliary ship. Her coal service ended in May 1919. In June 1919 she returned to the US with a cargo of World War I vehicles and weapons and unused ammunition. The US Navy decommissioned the Lake Pepin on 18 June 1919.[1] In 1923 she was, renamed Samoa purchased and operated by the Hammond Lumber Company. In 1936 she was sold to the Wheeler Logging Company of Portland, Oregon. In February of 1941 she was sold to W. A. Schaefer Company.
After the Attack on Pearl Harbor on 7 December 1941 the United States entered World War II. The Imperial Japanese Navy sent submarines to attack ships off Coastal California. On 18 December 1941 at about 5 am the Samoa was off Cape Mendocino, Humboldt County, California near Humboldt Bay, near the town of Petrolia, when fired 83lb artillery shells at her from her single 14 cm (5.5 in) naval gun. The Samoa was en route to San Diego with a load of lumber.I-17, far from home, was ordered to conserve torpedoes, so Commander Nishino Kozo opened the attack with artillery fire. Samoa the sub was spotted just before it fired on the ship. The captain of Samoa, Nels Sinnes, gave the order for the crew to report to their lifeboat stations and prepare the lifeboat. I-17 fired five shells at Samoa, none hit the ship, but shell fragments fell to the deck's stern. Ocean swells prevented I-17 from getting a direct hit. Nishino had orders to use only one torpedo on a merchant ship and then only if necessary. The swells and pitching deck made Nishino decided a torpedo was necessary. I-17 fired a torpedo while from Samoa. The Samoa watched as the torpedo's wake approached them amidships. They watched as the torpedo passed under the ship, continued and after passing the ship exploded. The explosion gave off smoke and flames, with torpedo fragments falling on Samoas deck. It was very dark and foggy that early morning and Nishino was unsure of the damage he had done to the Samoa. So he moved in closer to inspect the ship. At away from the ship the Samoas crew heard a Hi ya! from the sub. Captain Sinnes replied What do you want of us?, but there was no answer. Then the sub departed in the darkness. Sinnes then realized that the sub had inspected the side of the ship that had a damaged lifeboat form a previous storm and that the sub came close enough to see that the Samoa was listing, as the ship's engineers had been shifting water in the ballast tanks. Parts of the damaged lifeboat were hanging on the davit and it look like an explosion could have done the damage. Later Captain Sinnes thoughts on the sub's departure were confirmed. Captain Nishino sent a radio message to, that was near San Francisco, that he had sunk an American merchant ship. At 7 am daybreak the Samoa departed at full speed towards San Diego and arrived at port two days later. Samoa was scrapped in 1947 at Pittsburgh, Pennsylvania.[2] [3] [4] [5] [6] [7] [8] I-17 was sunk on 19 August 1943 by the New Zealand and United States Navy Kingfisher floatplanes, off Noumea.[9]
USS Lake Pepin / SS Samoa had eight sister ships built as Lake freighters. All nine were built in 1918 by McDougall-Duluth Company of Duluth, Minnesota with a 3,600 ton deadweight. The nine ships were built under United States Shipping Board (USSB) contract # 1320.[10]
