The Yangtze Patrol, from 1854 to 1941, was a prolonged naval operation to protect American interests in the Yangtze River's treaty ports. Initially the patrol was carried out by ships of the United States Navy's East India and Asiatic Squadrons. In 1922, the "YangPat" was established as a formal component and assigned to the Asiatic Fleet. Under the "unequal treaties", the United States, Japan, and various European powers were allowed to cruise China's rivers. They also patrolled coastal waters, protecting their citizens, their property, and their religious missions. The Yangtze is China's longest river, and very important to commerce. Ocean-going vessels were able to proceed as far upstream as the cities of Wuhan. This squadron-sized unit cruised the waters of the Yangtze as far inland as Chungking, more than 1,300 mi (2,100 km) from the sea, and occasionally far beyond.
19th century 
As a result of the "unequal treaties" imposed on China by Great Britain after the Opium Wars, China was opened to foreign trade at a number of locations known as "treaty ports" where foreigners were permitted to live and conduct business. Also created by the treaties was the doctrine of extraterritoriality, a system whereby citizens of foreign countries living in China were subject to the laws of their home country, not those of China. Most favored nation treatment under the treaties assured other countries of the privileges afforded Great Britain, and soon many nations, including the United States, operated merchant ships and navy gunboats on the waterways of China.
During the 1860s and 1870s, American merchant ships were prominent on the lower Yangtze, operating up to the deepwater port of Hankow 680 mi (1,090 km) inland. The added mission of anti-piracy patrols required U.S. naval and marine landing parties be put ashore several times to protect American interests. In 1874, the U.S. gunboat USS Ashuelot, reached as far as Ichang, at the foot of the Yangtze gorges, 975 miles from the sea. During this period, most US personnel found a tour in the Yangtze to be uneventful, as a major American shipping company had sold its interests to a Chinese firm, leaving the patrol with little to protect. However, as the stability of China began to deteriorate after 1890, the U.S. naval presence began to increase along the Yangtze.
20th century 
In 1901, American-flagged merchant vessels returned to the Yangtze when Standard Oil Company placed a steam tanker in service on the lower river. Within the decade, several small motorships began hauling kerosene, the principal petroleum product used in China for that company. At the same time, the Navy acquired three Spanish-built vessels (the gunboats USS Elcano, Villalobos and Callao), which it had seized in the Philippines during the Spanish-American War. These vessels became the core of the Yangtze River patrol for the first dozen years of the 20th century, but they lacked the power to go beyond Ichang onto the more difficult stretches of the river.
The USS Palos and Monocacy were the first American gunboats built specifically for service on the Yangtze river. The Mare Island Naval Shipyard in Vallejo, California built them in 1913. The U.S. Navy then had them disassembled and shipped to China aboard the American steamer Mongolia. The Kiangnan Shipyard in Shanghai reassembled them and put them into service in 1914.
Later in 1914, both vessels demonstrated their ability to handle the rapids of the upper river when they reached Chungking, which was more than 1,300 mi (2,100 km) from the sea, and then went further to Kiating on the Min River. In 1917, the U.S. entered World War I. The U.S. rendered the guns of Palos and Monocacy inoperable to protect Chinese neutrality. After China entered the war on the side of the allies, the U.S. Navy reactivated the guns.
In 1917, the first Standard Oil tanker reached Chungking, and a pattern of American commerce on the river began to emerge. On January 17, 1918, armed Chinese men attacked Monocacy and she was forced to return fire with her 6-pounder gun. Passenger and cargo service by American-flag ships began in 1920 with the Robert Dollar Line and the American West China Company. They were followed in 1923 by the Yangtze River Steamship Company, which stayed on the river until 1935, long after the other American passenger-cargo ships were gone.
In the early 1920s, the patrol found itself fighting the forces of deadly warlords and ruthless bandits. To accommodate its increased responsibilities on the river, the Navy constructed six new gunboats in Shanghai in 1926-1927 and commissioned in 1928 to replace four craft originally seized from Spain during the Spanish-American War that had been patrolling since 1903. All were capable of reaching Chungking at high water, and two year-round. USS Luzon and Mindanao were the largest, USS Oahu and Panay next in size, and USS Guam and Tutuila the smallest. These vessels gave the navy the capability it needed at a time when operational requirements were growing rapidly.
In the late 1920s, Chiang Kai-shek and the Northern Expedition created a volatile military situation for the patrol along the Yangtze. During the early-1930s, National Revolutionary Army took control of much of the north bank of the middle river. The climax of hostilities occurred in 1937 with the Rape of Nanking and the sinking of Panay by the Japanese. The USS Panay incident was the first loss of a US Navy vessel in the conflict which would soon become World War II.
After the Japanese took control of much of the middle and lower Yangtze, American gunboats entered into a period of frustrating inactivity and impotence. Just prior to the attack on Pearl Harbor, most of the ships on the Yangtze River Patrol were brought out of China, with only the smallest gunboats, Wake (the renamed Guam) and Tutuila remaining behind. Wake, at Shanghai, was subsequently captured by the Japanese. Tutuila, at Chungking, was turned over to the Chinese. When the other gunboats reached Manila, the Yangtze River Patrol was formally dissolved when, on 5 December 1941, Rear Admiral Glassford sent the message, "COMYANGPAT DISSOLVED". Subsequently, the evacuated ships were all scuttled, or captured with their crews and imprisoned by the Japanese, after the fall of Corregidor in mid-1942. Luzon was later salvaged and used by the Japanese. USS Asheville (PG-21) was sunk in battle 3 March 1942 and Mindanao was scuttled on 2 May.
Some patrols on the river were resumed in 1945, and included — among others — the destroyer USS Eaton and light cruiser USS St. Louis. When the Chinese Civil War reached the Yangtze Valley, this activity ended.
Popular culture 
USS San Pablo, the vessel in Richard McKenna's well-known novel The Sand Pebbles (1962), set in 1926, was modeled on the USS Villalobos, a 31-year old vessel originally captured from Spain. McKenna served aboard one of the newer river gunboats a decade after the time frame of his novel, as did William Lederer, the author of The Ugly American (1958). The film The Sand Pebbles was based on the book.
New York Times and Wall Street Journal best selling author, W.E.B. Griffin places the main character of his book "Semper Fi" within the Yangtze River Patrol. The opening chapters of this book provide an in depth illustration of both the mission and everyday life of United States Marines assigned to the Yangtze Patrol during the 1930s.
