A river in northern Maryland, which rises as a creek in southern Pennsylvania ; the Indian name means stream containing many large bends. The Civil War Battle of Monocacy, in which General Lew Wallace's Union forces prevented General Early's Confederates from reaching Washington, D.C., was fought on the banks of the river near Frederick, Md., 4 and 5 July 1864.

(PG--20: dp. 204 ; 1. 165'6" ; b. 24'6" ; dr. 2'5" ; s. 13.25k. ;cpl. 47; a. 2 6-pdrs., 6 mg.)

The second Monocacy (PG--20), a shallow draft gunboat built for service on the Yangtze River, was preconstructed at Mare Island Navy Yard in 1912 and then dismantled and shipped to Shanghai, China. She was laid down by the Shanghai Dock & Engineering Co., 28 April 1913 ; launched 27 April 1914 ; sponsored by Mrs. Andrew E. Carter ; and commissioned 24 June 1914, Lt. Andrew E. Carter In command.

Assigned to the 2d Division, Asiatic Fleet (popularly called the Yangtze Patrol), Monocacy sailed upriver from Shanghai 29 June 1914 to cruise between Ichang and Chungking. For the next 15 years, but for annual visits to Shanghai for overhaul, the gunboat patrolled the upper Yangtze with Chungking her upriver base. Monocacy protected American interests in treaty ports down the entire length of the Yangtze, at times escorting vessels, evacuating American citizens during periods of disturbance, and, in general, assisting U.S. Consulates in various Chinese cities.

On 10 January 1918, Chinese southern revolutionary troops attacked the little warship 50 miles above Chenglin. Monocacy prevented the bandits from firing on a Japanese steamer standing down stream. One crewman was killed and two others were wounded in the short but fierce fight. Five years later, in February and March 1923, the gunboat operated against bandits holding up American missionaries and firing upon U.S. flag vessels above Kiangnang, rescuing the Syracuse Medical Unit and a number of American families. Later that year, she protected U.S. river commerce from war lord armies and then in August, she established friendly relations with the Governor of Kiangsin Province.

Monocacy, continued her patrol operations on the upper Yangtze, reclassified PR--2 on 15 June 1928. She was placed in reserve 24 June 1929. Based at Shanghai, the gunboat cruised the lower river, making less frequent voyages to her original patrol area between Chungking and Ichang. She was placed in full commission once again 19 September 1931 to join other American naval vessels on the river in assisting the many Chinese forced from their homes by August floods which had inundated 34,000 square miles of land during the worst disaster in the rivers history. In 1933, Monocacy began to serve as station ship in various treaty ports during the cruising season, with her crew serving as a landing force in case of trouble.

Monocacy was at Kiukiang protecting American neutrality during the Japanese invasion of China, when on 29 August 1938 several mines exploded within 50 yards of the ship, showering the gunboat with fragments. She was then held at the port until the Japanese completed sweeping operations some days later. She decommissioned at Shanghai 31 January 1939. The veteran gunboat, one of the last "Old China Hands," who had never seen the land which she served so well, was towed to sea and sunk 10 February, in deep water off the China coast.

Monocacy (SP--1116) was purchased by the Navy 27 July 1917 from Philadelphia & Reading Railway Co., Philadelphia, Pa.; placed in service 25 September 1917 while being fitted out as a fleet tender at Philadelphia Navy Yard, Philadelphia, Pa,; and renamed Genesee (q.v.) before commissioning 17 October 1917.
