walking fire

Prithe Nunckle be content, this is a naughty night to swim in, now a little fire in a wild field, were like an old leachers heart, a small sparke, all the rest in bodie cold, looke here comes a walking fire.

To counter this the French introduced 'walking fire'. The infantry used man-carried automatic weapons to keep the defender pinned down with a continuous hail of bullets for those last dangerous yards.
