Border between Texas and Louisiana declared Neutral Ground
On this day in 1806, the United States and Spain signed an agreement establishing the Neutral Ground. After the Louisiana Purchase of 1803 the United States and Spain were unable to agree on the boundary between Louisiana and Texas. In 1806, in order to avert an armed clash, Gen. James Wilkinson and Lt. Col. Simón de Herrera, the American and Spanish military commanders respectively, entered into an agreement declaring the disputed territory Neutral Ground. The boundaries of the Neutral Ground were never officially described beyond a general statement that the Arroyo Hondo on the east and the Sabine River on the west were to serve as boundaries. Ownership of the strip was awarded the United States by the Adams-Onís Treaty in 1821.
