In April a Swedish force, under Colonel Falkenberg, was attacked and defeated at Moss by the Norwegians, under the command of Major-General Vincents Budde and Colonel Hvitfeld, who took four hundred prisoners and captured a large quantity of supplies. At the parsonage of Skieberg the Swedish general, Ascheberg, lay with 2,000 men and could hear the shooting at Moss; but the parson, Peter Rumohr, who had intercepted the correspondence between the Swedes at the parsonage and those at Moss, gave such exaggerated accounts of the defeat of the Swedes and of large reinforcements to the Norwegians, that General Ascheberg hastily broke camp and returned to Sweden. When King Charles, some time afterward, heard of this, he became so enraged at the minister that he caused him to be captured and brought to Sweden, where he died in prison. As the roads were becoming very bad, and Charles feared that the Norwegians contemplated cutting off his retreat, he suddenly withdrew from Christiania and shortly afterward attacked the city of Frederickshald. Here the citizens had armed themselves under the brave brothers Peter and Hans Kolbjörnson, nephews of Kield Stub, and half-brothers of Anna Kolbjörnsdatter, and the Swedes had to buy every step with blood. Charles captured the city on the night between the 3d and 4th of July, 1716, and the Norwegians had to retire to the fortress, Frederickssteen. That the enemy might not find shelter behind the houses against the shots from the fortress, the citizens put fire to the town. Peter Kolbjörnson commenced with his own house, and soon the whole city was in flames. Charles had to withdraw from Frederickssteen, with a loss of 1,500 men and three generals, to his headquarters at Torpum, intending to renew the siege as soon as he could get his heavy artillery from his transport ships at Dynekilen, near Svinesund. But in this hope he was disappointed, as the Norwegian naval hero, Peter Tordenskiold, by a daring attack shortly afterward, succeeded in capturing or destroying the whole transport fleet at Dynekilen.
