When was the "Regulations for the Order and Discipline of the Troops of the United States" printed?

The "Regulations for the Order and Discipline of the Troops of the United States," often referred to simply as the "Blue Book," was printed in 1779. This publication was a significant step in establishing a standardized approach to military training and discipline in the United States, influenced heavily by the practices of European armies, particularly those of Prussia. It served as a fundamental guide for the Continental Army, promoting organization and unity among the troops during a crucial period of the American Revolutionary War.

1779 is notable as it came after years of war, indicating a maturation of the American military establishment as it sought to professionalize its forces and improve upon the lessons learned in earlier engagements. The subsequent options, while close in time, do not accurately reflect the historical publication date of this important regulation, thereby supporting the choice of 1779 as the correct year.
