What is the first order to the sentry?

The first order to the sentry is to "Take charge of this post and all government property in view." This directive is foundational to the role of a sentry, encompassing both the responsibility for their designated area (the post) and the duty to safeguard government property. It establishes the expectation that a sentry not only observes and reports but actively ensures the security of both the immediate environment and any assets within sight.

This order emphasizes the importance of situational awareness and accountability, highlighting that the sentry must be proactive in protecting their assigned area. By taking charge, the sentry set the stage for all other duties, which include maintaining order, managing encounters with individuals, and responding effectively to any security threats.

Other options listed may represent important aspects of a sentry's duties but do not convey the preliminary responsibility that taking charge entails. For instance, keeping the peace is a part of maintaining security but falls under the broader task of taking charge. Similarly, patrolling and standing guard are aspects of a sentry's actions but are not the fundamental directive that defines their initial responsibility upon being assigned their post.
