German soldiers were encircled on the De Hoge Veluwe National Park and unexpectedly attacked the already liberated Dutch village Otterlo, leading to fierce fighting in hand-to-hand combat.

In the context of defeating Nazi-Germany, the army movements had their focus to go north as soon as possible; resulting in the liberation of Groningen at 13-16 April 1945.

As a big surprise to the allies (the military intelligence completely overlooked the gathering in Hoenderloo), the German troops decided to attack Otterlo during the night of 17 April.

[3] About 800-1000 German soldiers attacked the village from the north, resulting in fierce fighting and hand-to-hand combat.

The Germans were winning, until a couple of allied WASPS (flamethrowers) and regular tanks appeared on the battlefield and turned the tide.
