Sir James Ramsay was appointed to command the assault. The river Maine had to be crossed, and he sent off Lieutenant Robert Ramsay of his own regiment to obtain boats from the peasantry. The disguise in which he went was seen through, and he was taken prisoner and carried to the castle. A few boats were, however, obtained by the Swedes. The river is here 300 yards wide, and the central arch of the bridge had been blown up by the Imperialists, a single plank remaining across the chasm over the river 48 feet below. The bridge was swept by the heaviest cannon in the fortress, and a passage appeared well nigh hopeless. On the afternoon of the 5th of October the party prepared to pass, some in boats, others by the bridge. A tremendous fire was opened by the Imperialists from cannon and musketry, sweeping the bridge with a storm of missiles and lashing the river to foam around the boats. The soldiers in these returned the fire with their muskets, and the smoke served as a cover to conceal them from the enemy. In the meantime Major Bothwell of Ramsay's regiment led a company across the bridge. These, in spite of the fire, crossed the plank over the broken arch and reached the head of the bridge, from whence they kept up so heavy a fire upon the gunners and musketeers in the lower works by the river that they forced them to quit their posts, and so enabled Sir James Ramsay and Sir John Hamilton to effect a landing. Major Bothwell, his brother, and the greater part of his followers were, however, slain by the Imperialists' fire from above. The commandant of the castle now sallied out and endeavoured to recapture the works by the water, but the Scotch repelled the attack and drove the enemy up the hill to the castle again. The Scottish troops having thus effected a lodgment across the river, and being protected by the rocks from the enemy's fire, lay down for the night in the position they had won. Gustavus during the night caused planks to be thrown across the broken bridge and prepared to assault at daybreak. Just as morning was breaking, a Swedish officer with seven men climbed up the hill to reconnoitre the castle, and found to his surprise that the drawbridge was down, but a guard of 200 men were stationed at the gate. He was at once challenged, and, shouting “Sweden!” sprang with his men on to the end of the drawbridge. The Imperialists tried in vain to raise it; before they could succeed some companions of the Swedes ran up, and, driving in the guard, took possession of the outer court. Almost at the same moment Ramsay's and Hamilton's regiments commenced their assault on a strong outwork of the castle, which, after two hours' desperate fighting, they succeeded in gaining. They then turned its guns upon the gate of the keep, which they battered down, and were about to charge in when they received orders from the king to halt and retire, while the Swedish regiment of Axel-Lilly and the Blue Brigade advanced to the storm.
