What kind of preparation might Dahl and Coke have undertaken in anticipation of the Germans' return?

Strengthening defenses is a logical preparation for Dahl and Coke in anticipation of the Germans' return. This action reflects a strategic military approach where forces would fortify positions to better withstand an attack, ensuring that they could protect themselves and maintain control over their area. It suggests a proactive stance, readying themselves for potential conflict, which aligns with military protocol during war.

In a wartime context, gathering supplies would also be important, but Dahl and Coke's specific actions focus more on direct military readiness rather than logistical support. Evacuating personnel might be appropriate if the situation appeared dire, but it wouldn't convey a readiness to engage in defense. Conducting reconnaissance could provide valuable intelligence, but without the foundational strength of defenses, that information alone wouldn't suffice to protect against an incoming threat effectively.
