fall in

The camp is mostly under water, and when the "Fall-in" is sounded we do it quite easily.

Rest had just been commanded a few minutes when the command to "fall-in" was sounded.

How could a man travel forward from rustic deer-poaching to such tragedy-writing, and not fall-in with sorrows by the way?

Soon the fall-in order was given, and the older rookies fell in under arms.

It was at 4.30 when the Regiment received orders to "Fall-in."
