A lookout at one of the mastheads now shouted that he could make out a black mass on the ice near Amsterdam, and believed that it was a large body of troops. Every preparation had already been made on board the ships for the fight. The Good Venture lay on the outside tier facing Amsterdam, having been placed there because she carried more guns than any of the other vessels, which were for the most part small, and few carried more than four guns, while the armament of the Good Venture had, after her fight with the Don Pedro, been increased to ten guns. The guns from the vessels in the inner tiers had all been shifted on to those lying outside, and the wooden fort literally bristled with cannon. A quarter of an hour after the news that the Spaniards were on their way had been given, three hundred men with arquebuses were ferried across the channel, and were disembarked on to the ice. They were divided into five companies of sixty men each, under the lieutenants; the captain remained to superintend the defence of the ships. The Dutch sailors were as much at home on their skates as upon dry land, and in high spirits started to meet the enemy. It was a singular sight to see the five bodies of men gliding away across the ice. There was no attempt at formation or order; all understood their business, for in winter it was one of their favourite sports to fire at a mark while skating at a rapid pace. It was two miles from the spot where the ships lay frozen up to Amsterdam. The Spaniards, a thousand strong, had traversed about a third of the distance when the skaters approached them. Keeping their feet with the utmost difficulty upon the slippery ice, they were astonished at the rapid approach of the Dutchmen. Breaking up as they approached, their assailants came dashing along at a rapid pace, discharged their arquebuses into the close mass of the Spaniards, and then wheeled away at the top of their speed, reloaded and again swept down to fire. Against these tactics the Spaniards could do little. Unsteady as they were on their feet the recoil of their heavy arquebuses frequently threw them over, and it was impossible to take anything like an accurate aim at the flying figures that passed them at the speed of a galloping horse. Nevertheless they doggedly kept on their way, leaving the ice behind them dotted with killed and wounded. Not a gun was discharged from on board the ships until the head of the Spanish column reached the edge of the water, and discovered the impassable obstacle that lay between them and the vessels. Then the order was give to fire, and the head of the column was literally swept away by the discharge.
