I have not studied this war in detail but I managed to find some details. I will look some further and hopefully update this post further:
Battle of Lier, April 18 1808
Lier, April 18
On 15 April, just two days after Skalbukilen, a larger Swedish force crossed the border again. It was the 1st Swedish brigade, which marched from the south towards Kongsvinger fortress. The force was about 900 men. Against them they had de Seus's brigade of about the same number of men. The Norwegian force consisted of a grenadier battalion from the Oppland Regiment, three companies from the Norwegian Light Battalion, a half-battery of three-pounder guns with four cannons and four amuseettes, i.e. one-pounder guns. The Norwegian guards gradually withdrew in front of the Swedish advancing forces. The idea of the withdrawal was to draw the Swedish forces into the fortifications in Lier, five kilometers south of the fortress, where de Seus's brigade was waiting. The fortifications in Lier were about 940 meters wide and had a protruding redoubt (a small round and closed entrenchment) a bit in front of the main fortification. Such a redoubt would break up the formation of the attackers as early as possible, but also prevent attacks from the east. The scaffolding was on its left wing next to a steep hill that went down towards Lake Tarven, and on its right wing out towards an open area that looked out towards Lake Føskersjøen. The right flank was the weak point of the position. If the enemy passed between the fortification and the lake, it could come up to a rear height and from there fire on the position. In front of the scaffold, there was open terrain that sloped down from the scaffold and gave the defenders a good view of the attackers.
The commander of the Lier position was Major Kreutz and he had about 900 men at his disposal. Some of them were also rural soldiers, i.e. untrained boys and men who had not yet been drafted and therefore had little military value. He deployed from the left three light companies, in the middle was the grenadier company Grüner and out to the right the Sadoline grenadier company. Four three-pounder guns were placed at Liergården in the far south, two amuseettes were placed on the left wing and two were placed in the redoubt. The reserves were located at Kongsvinger, and Kreutz had no available reserves in the position. This disposition was due to the fact that de Seue was afraid that the Swedes would come towards Kongsvinger from other directions than over Lier.
When the Swedes got as far as Lier positions, they stopped. At 9 o'clock in the morning the attack on Lier redoubt started. Swedish Captain Matern attacked the right wing of the redoubt without much success. He was out early and had to retire. They were left waiting in a grove – hidden from the Norwegians in the positions. The Norwegians thought the Swedes were defeated for good.
The main Swedish forces were waiting for word from Major Cederström and his third column – who had gone around the position to attack the fortification in the rear by crossing the ice on Vingersjön. While they were waiting, the Swedish Commander-in-Chief Gustaf Mauritz Armfelt arrived. Finally, word came from Cederström that the ice on Lake Vingersjön was too unsafe. Armfelt therefore had to replan and ordered Cederström to go south of the lake to attack the redoubt from the side. In the meantime, the other Swedish forces would make life miserable for the Norwegians.
Early in the afternoon, the attack started by the Swedes shelling the redoubt with cannons for a while. After that, they tried to storm it several times, without success. Armfelt therefore gave the order to retreat, but the order was never carried out.
Cederström's forces had been observed, and Major Kreutz ordered parts of Sadolin's company to reinforce the defenses on the left wing. The order was misunderstood by Captain Sadolin, who took his entire company with him. He emptied the entire right wing of the redoubt and made it possible for Captain Matern to take up a position to fire on the Lier positions from the rear. Captain Sadolin quickly moved his company to the left wing. Instead of staying in the position, he attacked with the whole company down the steep slope towards Tarvensjön. Here he and his men were met by Swedish fire and did not cross a strong stream. He lost 30 percent of the company – dead or wounded.
The situation was now precarious for the Norwegians. The right wing was lost, there was not much ammunition left, and much of the force had fallen. The Swedes noticed this, who launched a storm attack(Upplands Regemente) in the front. The redoubt fell and the whole redoubt was disbanded. Major Kreutz ordered a general withdrawal. The defeat was almost total. 54 Norwegians fell and over 100 were captured. It is not known how many people were wounded. The Swedes had only 5 dead, but as many as 83 wounded. The Norwegians were able to save some of the cannons, which at that time was very important.
The loss of the Lier Position was a hard blow to the Norwegian army leadership. The Swedes held the area until May 30, when they withdrew pretty much across the board. The events further south made it necessary, much to the surprise of the Norwegians, who could not follow.

https://en.wikipedia.org/wiki/Battle_of_Lier_%281808%29Re-capture of positions at Broby and Prästebakke June 14, 1808
This is not much of a battle. The Västmanland Regiment and other forces took the positions while the Norwegians withdrew without fighting.
Skirmishes June 30-July 2, 1808 at Vassbotten and Enningdalsbro
A Norwegian detachment under Captain Huitfeldt attacked the Swedish position at Vassbotten. If the Huitfeldts force was the same as during the battle of Prästebakke June 10, it should consist of infantry from the Sondenfjeldske Regiment (page 28, plate 1 in Wilsons volume 3) together with some militia.
Google translation from "Sveriges Krig 1809-1809"
At dawn Huitfeldt attacked with 150 men the Swedish outpost of 300
Västmanland and Jämtland infantry under the captain of Västmanland's
regiment Count H. M. Cronhjelm at Vassbotten . After a brief exchange of gunfire
the Norwegians withdrew again with insignificant
loss. Huitfeldt's detachment took up a position at Enningdalsbro.
Here he was attacked on the night of 1-2 .
July by a Swedish reconnaissance detachment and withdrew slightly
but took their previous position, since the Swedes
returned to Vassbotten with some prisoners.
