These "trading houses" were later established at the junction of the Clear Fork and West Fork of the Trinity River in present-day Fort Worth. At this river junction, the U.S. War Department established Fort Worth in 1849 as the northernmost of a system of 10 forts for protecting the American Frontier following the end of the Mexican–American War. The city of Fort Worth continues to be known as "where the West begins," whereas Dallas is known as "where the East ends". A line of seven army posts was established in 1848–49 after the Mexican War to protect the settlers of Texas along the western American Frontier and included Fort Worth, Fort Graham, Fort Gates, Fort Croghan, Fort Martin Scott, Fort Lincoln, and Fort Duncan. Originally 10 forts had been proposed by Major General William Jenkins Worth (1794–1849), who commanded the Department of Texas in 1849. In January 1849, Worth proposed a line of 10 forts to mark the western Texas frontier from Eagle Pass to the confluence of the West Fork and Clear Fork of the Trinity River. One month later, Worth died from cholera in South Texas. General William S. Harney assumed command of the Department of Texas and ordered Major Ripley A. Arnold (Company F, Second United States Dragoons) to find a new fort site near the West Fork and Clear Fork. On June 6, 1849, Arnold, advised by Middleton Tate Johnson, established a camp on the bank of the Trinity River and named the post Camp Worth in honor of the late General Worth. In August 1849, Arnold moved the camp to the north-facing bluff, which overlooked the mouth of the Clear Fork of the Trinity River. The United States War Department officially named the post Fort Worth on November 14, 1849. Native American attacks were still a threat in the area, as this was their traditional territory and they resented encroachment by European-American settlers, but people from the United States set up homesteads near the fort. E. S. Terrell (1812–1905) from Tennessee claimed to be the first resident of Fort Worth. The fort was flooded the first year and moved to the top of the bluff; the current courthouse was built on this site. The fort was abandoned September 17, 1853. No trace of it remains. As a stop on the legendary Chisholm Trail, Fort Worth was stimulated by the business of the cattle drives and became a brawling, bustling town.
