At last Gustavus resolved upon an attack. He led his troops against the intrenchments of Wallenstein, which resembled a fortress rather than a camp. The Swedes clambered over the intrenchments, and assailed the imperialists with as much valor and energy as mortals ever exhibited. They were, however, with equal fury repelled, and after a long conflict were compelled to retire again behind their fortifications with the loss of three thousand of their best troops.
