The Battle of the Barrier Forts (also known as the Battle of the Pearl River Forts) was fought between American and Chinese forces in the Pearl River, Guangdong, China in November 1856 during the Second Opium War. The United States Navy launched an amphibious assault against a series of four forts known as the Barrier Forts near the city of Canton (modern-day Guangzhou). It was considered an important battle by the British whose interest lay in capturing Canton.
Sailing off the Chinese coast, and had received news of the beginning of the Second Opium War. The two sloops-of-war were tasked with protecting American lives by landing a 150-man detachment of marines and sailors in Canton.
After a peaceful landing the Americans occupied the ancient city. Commanded by both Commodore James Armstrong and Captain Henry H. Bell, arrived in Canton's harbor and learned of the occupation. San Jacinto then landed a shore party of her own.
On November 15, 1856, after a brief stay and no military contact, the force withdrew from the city. During the withdrawal, Commander Andrew H. Foote of the Portsmouth rowed out to his ship. As he rowed past the Pearl River Forts, the Chinese garrison fired on the small American boat a few times but the withdrawal continued.
The next day the U.S. seamen had constructed a plan to attack Canton's citadels in retaliation for the Chinese attack on Commander Foote.
Now a force of one steam frigate the (San Jacinto), and two sloops-of-war, the naval squadron under James Armstrong made their way up the Pearl River and launched an attack on Canton's coastal forts. USS Portsmouth closed in on the nearest of the four citadels and fired the initial salvo on November16.
For two hours her bombardment continued until the Chinese batteries were silenced. After this first engagement, Chinese and American officials decided to try to settle the matter diplomatically. This failed and on November20, Commodore Armstrong ordered his ships to fire again on two more of the Chinese forts.
This bombardment lasted until the Chinese batteries weakened slightly, after which the Levant, commanded by William N. Smith, received 22 cannonball shots in her sails, rigging, and hull. Under cover of their ships' fire, a storming party of 287 troops led by Foote landed unopposed. Spearheading this force were about 50 marines under Captain John D. Simms and a small detachment of sailors.[3] [4] They quickly captured the first enemy fort, then used its 53 guns to attack and capture the second fort.
When taking the second position, the Chinese launched several counterattacks with some 3,000 Qing Army soldiers from Canton. In a few more days of intense combat until the 24 November the U.S. force, with help from the blockade, pushed back the attacking Chinese army, killing and wounding dozens of the attackers, capturing two more forts and spiking 176 enemy guns.
Chinese casualties were an estimated 250 to 500 killed or wounded. The Americans land forces sustained seven killed and 22 wounded. USS Levant suffered one killed and six wounded in her exchange with the Pearl River Forts. Portsmouth was hit 18 times and the Levant 22 times, but neither was seriously damaged.[5]
After James Armstrong's attack on the Chinese fortifications, diplomatic efforts began again and the American and Chinese governments signed an agreement for U.S. neutrality in the Second Opium War. This ended the United States' participation in the conflict until 1859, when Commodore Josiah Tattnall III in the chartered steamship Towey Wan participated in the Battle of Taku Forts, which was ultimately unsuccessful. In 1857, the British and French would use Pearl River to attack Canton from water, resulting in the Battle of Canton. America's opening of Asia continued into the 1860s with conflict, such as the Battle of Shimonoseki Straits and a following bombardment, as well as an expedition to Korea in the 1870s.
