A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies.
A river gunboat is a type of gunboat adapted for river operations. River gunboats required shallow draft for river navigation. They would be armed with relatively small caliber cannons, or a mix of cannons and machine guns. If they carried more than one cannon, one might be a howitzer, for shore bombardment. They were usually not armoured. The fictional USS San Pablo described in Richard McKenna's The Sand Pebbles is an example of this class of vessel, serving on the US Navy's Yangtze Patrol. Stronger river warships with larger guns were river monitors.
The second USS Panay (PR–5) of the United States Navy was a Panay-class river gunboat that served on the Yangtze Patrol in China until being sunk by Japanese aircraft on 12 December 1937 on the Yangtze River.
The Amethyst incident, also known as the Yangtze incident, was a historic event that occurred on the Yangtze River for three months in the summer of 1949, during the late phase of the Chinese Civil War. The incident involved the Communist People's Liberation Army (PLA), who were in the middle of a river-crossing offensive to overthrow the Nationalist Government, and four British Royal Navy ships HMS Amethyst, HMS Black Swan, HMS Consort and HMS London. The British warships, whose claimed right of passage, per Treaty of Tientsin, along the Yangtze had been unchallenged previously since the late Qing dynasty, came under bombardment by PLA artillery and were forced to withdraw permanently from Chinese territorial waters.
The Yangtze Patrol, also known as the Yangtze River Patrol Force, Yangtze River Patrol, YangPat, and ComYangPat, was a prolonged naval operation from 1854 to 1949 to protect American interests in the Yangtze River's treaty ports. The Yangtze Patrol also patrolled the coastal waters of China where they protected U.S. citizens, their property, and Christian missionaries.
The Nanking Incident occurred in March 1927 during the capture of Nanjing by the National Revolutionary Army (NRA) in their Northern Expedition. Foreign warships bombarded the city to defend foreign residents against rioting and looting. Several ships were involved in the engagement, including vessels of the Royal Navy and the United States Navy. Marines and sailors were also landed for rescue operations including some 140 Dutch forces. Both Nationalist and Communist soldiers within the NRA participated in the rioting and looting of foreign-owned property in Nanjing.
