fieldpiece

Bart made out a long fuse trailing three feet or more over the side of the old fieldpiece.

Mick Kennedy trained his one eye like a fieldpiece upon the locality suggested.

One of the soldiers afterward told me that when the governor landed he was greeted with thirteen rounds from a fieldpiece.

They've brought up a fieldpiece, from goodness only knows where!

Before it grew too hot, they took me out to see the barracks and a ramshackle old fieldpiece which they seemed to idolise.
