On Sunday, April 15, a Canadian tank division, after the liberation of Arnhem, was moved from the Betuwe to the Veluwe. Their first objective was 'Fliegerhorst Deelen,' the airfield at Deelen, which they successfully captured that day. The division split into two groups, taking different routes: the main force advanced through Park De Hoge Veluwe towards Otterlo. Heavy resistance near Otterlo forced the troops to halt their advance that day. The next morning, they decided to proceed.

That day, the Canadian tanks traveled from Deelen via Oud Reemst and Mossel to the Valenberg behind the former bullet catchers on the Eder heath. They stayed there that night in a secured position. Unfortunately, five Canadians were killed during a reconnaissance mission in a firefight. After being resupplied with fuel and ammunition, the tank column departed on Monday, April 16, from the Valenberg via the Koeweg and Hessenweg to the Goudsberg. Along the way, the tanks regularly took out German positions.

However, the German resistance also caused significant losses on the Allied side, with many wounded in urgent need of evacuation. Soldier Horace Basil Parker rushed into the regiment's aid post and boarded a Bren carrier. He bravely drove through several German positions, which heavily fired upon his vehicle. Parker reached the tanks and loaded the wounded into his carrier. When he arrived at a German position that had been significantly reinforced since his first trip, he had no choice but to stop. A German officer stepped out and ordered him to drive to a nearby house where he and his passengers would be taken prisoner. Parker looked at the machine guns firing at his carrier and slammed on the gas. As Parker sped down the road towards the Canadian lines, bullets whizzed over his head and struck the thinly armored sides of his carrier. But he and his wounded comrades remained unharmed during this dangerous mission. Parker's extraordinary bravery was later recognized with a military medal.

By noon, the Canadian tanks had positioned themselves at the Goudsberg. From that position on the Goudsberg, the Canadians fired a few salvos towards Lunteren, but they did not cause much damage. Meanwhile, they were harassed by about three hundred German SS soldiers from the direction of Wekeromse Zand. The Canadians decided to call in artillery support and began shelling the area from the Lage Valkseweg. Only eight SS soldiers were captured, while the others either fled or perished in the battle. The forests were left burning and smoldering: the fight left a devastating trail. By evening, the Sherman tanks, accompanied by infantry, drove to Lunteren. They were greeted with a grand welcome by the local population, as Lunteren was finally liberated. According to the Canadian report, forty-two German soldiers were captured. It further noted: 'Not a shot was fired and 2 officers and 40 ORs meekly surrendered, the town was ours!'
