Final answer:
The guards abandon the marchers due to being overwhelmed, bribed, or coerced, and may also desert out of fear or self-preservation.
Step-by-step explanation:
The guards abandon the marchers because they are overwhelmed by the situation and do not know whom to trust. In some cases, the guards may have been bribed or coerced to leave their positions. In other instances, the guards may have been unable to handle the heat and pressure of the situation, causing them to flee.
An example of guards abandoning the marchers can be seen in the context of the American Revolution. During the Battle of Lexington and Concord, British soldiers were marching back to Boston when they were exposed and attacked by militia and minutemen hiding in the woods.
The British soldiers were unable to defend themselves and were forced to retreat under heavy fire, resulting in the guards abandoning the marchers.
It is also important to note that the guards may have deserted due to fear or self-preservation. When faced with an overwhelming or unpredictable situation, individuals may prioritize their own safety over their duty to protect others.
