In the 8th General Order, what action is a sentry instructed to take?

The 8th General Order specifically instructs a sentry to give the alarm in case of fire or disorder. This directive emphasizes the responsibility of a sentry to remain vigilant and alert to any potential emergencies or disturbances that could compromise safety and security. It reinforces the critical role of a sentry in protecting personnel and property, ensuring that they are proactive in communicating urgent matters.

Remaining watchful for fire or disorder not only reflects properly on the sentry's duties but also establishes the importance of swift communication for the safety of everyone involved. This action is essential in maintaining order and quick response to any threats that may arise.

Other options present different responsibilities or actions that a sentry might take under various circumstances, but they do not pertain specifically to the 8th General Order, which solely focuses on the need to raise the alarm for emergencies.
