 They were repulsed, and the Swedes left one of their assault bridges behind, which the Danes captured and measured.They found that the Swedish assault bridges were 36 feet long, and thus they realised that they could render these bridges useless by making the ice free parts of the moats wider than that.The moats and the beaches had been kept free of ice, and now the ice free zones were widened to 44 feet with help from 600 Dutch marines.
