Because politicians could never agree
Up until this declaration, colonists have used non-violent means, such as petitions, to protest the abuses of King George III. Each attempt to request peaceful negotiations was met by neglect and more abuse.
Additionally, colonists tried to appeal to Parliament and other British citizens for help. These attempts were ignored. Colonists appealed to British citizens' sense of justice, to their shared heritage and culture, and to their economic connection. These attempts failed, however, and the colonies have no other choice but to declare separation. In doing so, the new separate nation will view British citizens as enemies during wartime, and as friends in peacetime.

Cheat Mountain, September 16, 1861. We have survived three brigades of Confederate opposition, and are looking towards moving forward.

We have forced the Rebels back to where they came from.
It was discovered that General Lee was the presiding commander over the Rebel forces! It is believed that the Confederates were unorganized and without proper leadership. These combinations lead to the Rebel defeat at the hands of our three-hundred man force. Once Col. John Washington was killed in action, the confederates accepted defeat. In fact, the enemy retreated before our reinforcements arrived.
