Battle When the vanguard of Colonel Gahn's column later in the day reached Captain Nægler's companies in the Trangen pass they immediately attacked, and the attack was so heavy that Nægler had to call for reinforcements. But after about an hour of fighting it still looked as if the Swedish troops were about to break through the Norwegian defensive lines at the Trangen pass. While this was going on, Colonel Staffeldt brought the main force eastward from Sønsterud towards Nyen which was the sharpshooter division's main position, to block the crossing north of the river Flisa.

Twice Major Ræder and his officers managed to turn the wavering Norwegians, and it was during this phase of the battle that the Norwegian Captain Nicolay Peter Drejer distinguished himself when he climbed up on a pine stump and commanded his troops while shooting at the Swedes. He was able to fire almost continuously against the enemy since two grenadiers helped him reload his
