Why did the Virginia governor send George Washington to Fort Duquesne?

The location gave the French the opportunity to trade with Native American groups in the Ohio Country and deter the growth of British trade and settlement in North America. In spring 1754, Major George Washington led an expedition of 300 Virginians toward Fort Duquesne to force the French to abandon the site.

freedom of speech is also protected by the 1 amendment.

explanation:

here is pretty much what the 1st amendment says:

congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.

according to this text from the preamble to the declaration, who gives men their unalienable rights?
