After their little conversation, the German brothers had resumed their search for England in silence. Which is really something that might seem remarkable so far as Prussia is concerned, that he can possibly be silent, However, one does not become a feared military power without knowing something of tactics. So when he spots that small orb of light bobbing in front of England, he merely gestures for Germany to halt.

There are a few more hand motions that follow, suggesting they flank the island and attempt to take him by surprise before England gets too much closer to the residential building or any other more populous areas. (Well, the gesturing isn't quite so meaningful. It rather cuts off after he does the signal meaning ambush. Still, he'd like to think that Germany gets why they want to follow Prussia's plan.)
