What significant event in recruiting began in 1776?

The correct answer highlights a crucial moment in American history when the Continental Army was officially established. In 1776, as the United States sought independence from British rule, there was a necessity to organize a formal military force. This led to the raising of Continental Soldiers, marking the beginning of structured military recruitment as part of the revolutionary efforts.

This event not only signifies the initiation of organized recruitment efforts for military service but also illustrates the early foundations of a military force that would eventually evolve into the modern United States Army. The success of these early recruitment efforts was pivotal in securing support and manpower for the revolutionary cause, showcasing the importance of recruiting in securing the nation's independence.

In contrast, the other options pertain to different historical contexts or developments that occurred after 1776 and do not represent the foundational moment when military recruitment began in America.
