Battle of Hemnes Church
On 20 April, Christian August sent two companies under Captains Heyerdahl and Zarbell toward Hemnes. Rumors soon spread that the Swedes were advancing, and Heyerdahl withdrew with his company and returned to Fetsund. Zarbell remained at the pass west of the Lund farm, east of Hemnes Church. He advanced toward the farm and found a Swedish rifle company, which was driven from its position and forced back almost half a mile to Opsal and Krok in Rødenes.

These were the northernmost Swedish positions, and brigade commander Colonel Cederström was also there. The company commander was ordered to return and confront the Norwegian company, which had remained near Lund. The Swedes tried to drive Zarbell and his men out of position, but failed. After losing a quarter of their strength, the Swedes had to give up and withdraw.

The lines then remained quiet for a while, and Zarbell used the time to familiarize himself thoroughly with the ground leading down toward, and partly behind, the Swedish lines.
