A grenade had come flying into the foxhole where Dane and Harding had felt reasonably safe.
With morning he was half a mile away, in a foxhole less than sixty yards from the massive outer perimeter of the arena.
The foxhole had two entrances, both well-concealed, and he had rigged elaborate warning devices should the vicinity be approached.
The shower of rock is somewhat reminiscent of Ungava's meteor spray or splintered debris forced down a soldier's foxhole.
And while an officer wouldn't be expected to pitch a tent, he would dig his own foxhole, unless he was well up in grade.
