USS Wissahickon (SP-852)
The second USS "Wissahickon" (SP-852), which also served as USS "SP-852", was a United States Navy patrol vessel in commission from 1917 to 1918. Construction and early civilian career. "Wissahickon" was laid down in 1899 by George Lawley & Son at Neponset, Massachusetts, as the private single-screw steam yacht "Valda", with a composite hull made of an iron frame with wood planking. "Valda" was completed in 1900 and renamed "Wissahickon" in late 1901 or early 1902. She was the property of Mrs. Charles W. Henry of Philadelphia, Pennsylvania, when the United States entered World War I on  6 April 1917 and may have served in the Maine Naval Militia prior to her acquisition by the U.S. Navy. Acquisition and commissioning. In 1917, the U.S. Navy acquired "Wissahickon" from Mrs. Henry for use as a section patrol vessel during World War I. Records concerning "Wissahickon"s acquisition and commissioning are vague, somewhat contradictory, and incomplete. It appears that U.S. Navy personnel reported aboard "Wissahickon" as early as April 1917, although one record source states that the Navy did not acquire her from Mrs. Henry until 13 July 1917. No primary source states her commissioning date; her ship's log  starts on 20 August 1917 - stating that she was under the command of Lieutenant, junior grade, E. W. Haskell, USNRF on that date - but one secondary source states that she was not commissioned until 3 October 1917. At any rate, "Wissahickon" was commissioned sometime between April and early October 1917. Sources differ as to whether she was commissioned without her name as USS "SP-852" or as USS "Wissahickon" (SP-852), with her name being changed in 1918 to USS "SP-852". U.S. Navy service. The Navy considered "Wissahickon"/"SP-852" too light for "distant service" in European waters, so she was placed in the  Naval Coast Defense Reserve and assigned to the 1st Naval District in northern New England. Initially based at Rockland, Maine, she began patrols in the vicinity of that port. She spent most of the winter of 1917-1918 moored to a pier there; in January 1918, all of her officers and enlisted men became ill with common colds and sore throats, and the ship was quarantined until the diseases ran their course. When her crew had returned to good health, she returned to patrol duty off Rockland. In mid-summer 1918, she was reassigned to duty at Boston, Massachusetts, where  she arrived on 20 August 1918. She operated from the section base at East Boston, Massachusetts, for the rest of World War I and into January 1919. Apparently sometime between September and November 1918, and definitely by 1 January 1919, her name was changed from USS "SP-852" to USS "Wissahickon" (SP-852). Disposal. Late in January 1919, "Wissahickon" moved to Camden, Maine. She was stricken from the Navy List on 10 February 1919 and was decommissioned at Camden on 12 February 1919. On 15 February 1919, she was ordered returned to Mrs. Henry.
