Theodore Slagheck, exercising power with barbarous cruelty and outrage, had himself taken the command of the castle of Westeras. He caused all the fences of the neighborhood to be broken down, in order to be able to use his cavalry without impediment against the insurgent peasants, who, on April 29th, approached the town. Both horsemen and foot, with field-pieces, marched against them; and Gustavus, who had interdicted his men from engaging in a contest with the enemy, intending to defer the attack till the following day, was still at Balundsas, half a mile from the town, when news reached him that his young soldiers were already at blows with their adversaries, and he hastened to their assistance. The Dalecarlians opposed their long pikes to the onset of the cavalry with such effect that, more than four hundred horses having perished in the assault, they were driven back on the infantry, who were posted in their rear, and compelled to flee along with them, while Lawrence Ericson pushed into the town by a circuitous road and possessed himself of the enemy's artillery in the market-place. When the garrison of the castle observed this, they set fire to the houses by shooting their combustibles, and burned the greatest part of the town. The miners and peasants dispersed to extinguish the flames or to plunder, bartered with one another the goods of the traders in the booths, possessed themselves of the stock of wine in the cathedral and the council-house, seated themselves round the vats, drank and sang. The Danes, reenforced from the castle, rallied anew, and the victory would undoubtedly have been changed into an overthrow had not Gustavus sent Lawrence Olaveson, with the followers he had kept about him, again into the town, where, after a renewal of the conflict, the foe was put to an utter rout. Many cast away their arms, and threw themselves, between fire and sword, into the waters. Gustavus caused all the stores of spirituous liquors to be destroyed, and beat in the wine casks with his own hand.
