Kurt Martti Wallenius

Here, he was given the command of the northern group in the failed March 1918 Viena expedition, which tried to annex parts of East Karelia to Finland.

When the Winter War began, the Commander-in-Chief of Finnish troops Mannerheim appointed Wallenius as the commander of the Lapland Group.

Once the front in Lapland had stabilized, Wallenius handed the command over to Swedish volunteers under Lieutenant General Ernst Linder in February 1940.

Wallenius and most of his troops were sent to the southernmost point of the front to western shore of the Bay of Viipuri, where the Red Army had crossed the frozen gulf.

Wallenius failed to prevent the Red Army from gaining a foothold from the western shore of the bay, and there were reports that he was drinking heavily.

Wallenius was dishonorably discharged in early March 1940, after only three days in command, and replaced by Lieutenant General Karl Lennart Oesch.
