You are Lieutenant Colonel George Washington, an American-born English soldier. You have been sent by the Lieutenant Governor of Virginia to defend the Ohio Valley. The French want access to the Ohio Valley so they can continue to use it for fur trading. You have orders to stop them, because the Lt. Governor insists that the Ohio Valley is part of Virginia.
You assemble your soldiers and march to the Ohio Valley. This is the first command you have gotten, and you are eager to do a good job. If this goes well, you might get promoted to a full colonel, or even a general.

When you get to Ohio, it’s a total wilderness: you have marched for days and all you see are miles and miles of trees. You arrive at Fort LeBoeuf, one of the French forts, and deliver a polite letter asking the French to leave. The French commander informs you that they will not. You return to Virginia to inform the Lt. Governor of the bad news.
To secure the English claim on the Ohio Valley, another English military commander goes west to set up a fort. They have a difficult time building the fort, and before they are finished, the French attack and take over the fort. The French finish building the fort and name it Fort Duquesne. It takes days for the news of this event to reach you in Virginia.

When Lieutenant Colonel Washington hears about what happened to the English fort, what will he think?

What should Lieutenant Colonel Washington do next?
