depth charge

On investigation this was found to be merely disturbances caused by the explosion of the depth-charge.

At the beginning of the war the German depth-charge was a thing of contempt, and its English counterpart was nearly as useless.

Only the sharp lookout kept had saved them—that and the depth charge.

The depth-charge had fouled a trailing wire from some of my ‘stage scenery sky’ and been dragged along to detonate close astern.

The shock from the depth-charge—which appears to have detonated just about right to have the maximum effect—was terrific.
