In 1863, the U.S. Navy attempted to invade Confederate Texas through the Sabine Pass to gain access to Houston, the rail center of Texas. Guarding the pass was Fort Griffin, where on Sept. 8, 1863, Lt. Dick Dowling and 46 of his men used six cannons to defeat four gunboats and halt the invasion. In honor of the Texas defenders, a bronze statue of Dowling overlooks the 57.5-acre park. An interpretive pavilion illustrates the story of the battle, while a walking trail features historical markers. Four World War II ammunition bunkers stand witness to the site’s use by the U.S. Army Coastal Artillery Division.

Fort Towson was established in 1824 in response to a need to quell conflicts between lawless elements, Native American peoples, and settlers claiming the area as part of Arkansas Territory. The fort also served as an outpost on the border between the United States and Texas, which at that time was part of Mexico. Connected to the East by road, Fort Towson served as a gateway for settlers bound for Texas during the 1830s. Those passing through the area included Sam Houston, Davy Crockett, and Stephen F. Austin. When the Choctaw and Chickasaw were displaced from their lands in the Southeastern United States, the fort served as a point of dispersal upon their arrival in the west. The fort was also an important staging area for U.S. forces during the Mexican War of 1846. Fort Towson was abandoned in 1856 when the frontier moved west. During the Civil War, however, it served for a time as headquarters for Confederate forces operating in Indian Territory. In 1865 General Stand Watie surrendered his command near the fort to become the last Confederate general to lay down arms.

Fort O'Brien (Fort Machias) was built in 1775 and destroyed by the British in the same year. This state historic site is one of few Maine forts active during three wars—the American Revolution, the War of 1812 and the Civil War. Fort O'Brien's layout was altered several times over the 90 years it was active on this site; but the fort's important role in protecting the Machias River and its towns remained unchanged. It was refortified in 1777 and destroyed once again by the British in 1814. Well-preserved earthworks which overlook Machias Bay were erected for a battery of guns in 1863. The first naval engagement of the Revolution was fought offshore in 1775, five days before the Battle at Bunker Hill.
