This was a naval engagement between foreign ships and the Choshu Navy and part of the Shimonoseki Campaign in which the United States, England, France, and Holland sent warships into the Straits of Shimonoseki to attack the naval vessels under the control of the Lord of Choshu.  The Choshu Samurai had taken up the position of SONNO JOI (Expel the Barbarians), and wanted all foreigners removed from Japan.  The Choshu Clan, under Lord Mori Takachiba, ordered his Samurai to fire upon any foreign ships entering the Straits of Shimonoseki.  The first attack was against the US merchant steamer SS Pembroke. Following the attack, President Lincoln ordered the US Frigate USS Wyoming into the Straits to attack the Choshu Samurai navy.Later, French and British warships were sent into the area to protect their merchant ships.
