On 25 April 1945, after it was determined that the final German formations in Finnish territory were withdrawing, a 60-strong battle patrol led by Captain Valkonen was assigned to reconnoitre if Finnish Lapland was free from Wehrmacht forces. The detachment was assembled from 1st Company, Battle Group Loimu, Infantry Regiment 1, and departed on its mission at 1:00 pm the same day from southern Kilpisjärvi. The ski patrol advanced north-west towards Norway for around until it was split in two near the Saana fell. The smaller group would approach the Norwegian border along the road while the bulk of the patrol would continue with Captain Valkonen towards the three-country cairn farther off. They reached the cairn by 1:15 am on 26 April after skiing approximately more. Pioneer Antti Poikola attached a small flag of Finland to the cairn and the patrol reported back by radio that no Germans had been sighted on Finnish soil. Valkonen and his team shot three gun salutes at the cairn before leaving; the shots rang out across the fells and startled a Swedish border guard unit nearby.
