Document 5: Battle of Calcasieu Pass: The Battle of Calcasieu Pass was a minor skirmish fought on May 6, 1864, at the mouth of the Calcasieu River in southwestern Louisiana, during the American Civil War. It resulted in a Confederate victory. The participants of the battle were Lt. Benjamin Loring and Lt. C. W. Lamson on the Union’s side, and Col. W. H. Griffin on the Confederate side. The union brought along two naval vessels, the U.S.S Wave and the U.S.S Granite City. The U.S.S Wave did not prove too effective during the battle and was captured early on, it was soon turned into a Confederate cargo ship. The U.S.S Granite City was originally a confederate blockade vessel, but was captured in 1863 by the U.S.S Tioga (Union). The U.S.S Granite City was now back in the hands of the Confederates. Captain Joseph A. Brickhouse, a Confederate veteran, said, “We fought in the open prairie, bringing on the attack with four small pieces of artillery and less than 300 infantry, poorly armed, attacking in the open prairie two such boats as the Granite City and Wave - Union gunboats - and capturing them after an action of less than two hours and 40 minutes duration.” He described his own forces (Confederate) as unprepared, and he stated that they still had an easy battle that was short in duration. The Confederate forces in this battle were split up into five battalions. The first battalion was Creuzbauer's Battery, 5th Texas Artillery. Every soldier in this battalion was born in Germany, and they all migrated to the U.S during the Civil War. The second battalion was named Griffin’s Battalion, and was led by Col. William Henry Griffin. The third battalion was Spaight’s Battalion, led by Lt. Col. Ashley W. Spaight. And the final one was Daly’s Battalion, the only cavalry unit in the battle. The U.S.S Wave and the U.S.S Granite City received orders to proceed to Calcasieu Pass. When they arrived, immediately bombed an abandoned Confederate fort at the mouth of the river. The Gunboats were sent with money to purchase cattle from local southern farmers. The U.S.S Granite City ended up stealing cattle and horses from multiple farms. This prompted a Confederate attack. The local Confederate forces arrived quietly and prepared for a night-time attack on the Union forces. When the Union went to sleep, they let less-experienced soldiers man the guns. The Confederates seized the opportunity and moved their cannons closer. The cannons lined up 1,000 yards away from the gunboats, while the cavalry and foot-soldiers advanced. Numerous cannon shells penetrated the gunboat’s hulls. While the cavalry and foot-soldiers moved in, the artillery advanced as well, and finished off the vessels. On May 8th, Ella Morse, a Union Supply ship did not know of the Union casualties. Then brought moved up all the way to the other ships with supplies. When she noticed that confederates were manning the guns it was too late. They gunned the ship down. The Union Forces suffered many casualties. They lost the Ella Morse, the U.S.S Granite City, the U.S.S Wave, and the U.S.S New London. On the other hand, the Confederates did not lose too many soldiers. The Confederates only suffered a few men from each battalion.

During the war, he and Halleck Tustenuggee, another prominent Seminole leader in the war, met with General Walker Keith Armistead to negotiate, but negotiations broke down and the war resumed. As the war waned, Armistead used money to bribe several Seminole leaders to surrender, but Tustenuggee refused to be bribed and he continued to lead his band in fighting. When the war ended, his Seminole band was one of the few that remained in Florida. In 1843, Tustenuggee and 26 of his followers were forcibly migrated from Florida to New Orleans, Louisiana. They were transported by the USS "Lawrence" along with 65 other Native Americans and three black slaves. Tustenuggee then committed suicide by swallowing powdered glass.
