Blick was initially involved in organizing the movement of the volunteers in the region, but soon also traveled to Germany himself, joining the 27th Royal Prussian Jäger Battalion.

[1][2] Blick returned to Finland in 1918, taking part in the Finnish Civil War on the side of the Whites first as a platoon leader.

In 1920, Blick transferred to the Finnish General Headquarters to act as staff officer and was promoted to a captain.

During his time in this posting, in 1928, Blick was promoted to the rank of lieutenant colonel and served as the chairman of the school's honor council in 1929 and 1931.

[1][3] Following the end of the war in early 1940, Blick was initially posted into the headquarters of the peacetime III Corps and as the commander of the 3rd Division.

Later in 1940, he was made commander of the Itä-Savo Military District, keeping the posting until the start of the Continuation War in the summer of 1941.

[1] When the Finns, alongside Germans, attacked the Soviet Union in 1941, Blick initially commanded the 2nd Division.

1941 also saw Blick's promotion to major general and an award of Mannerheim Cross, the most distinguished Finnish military honour.

[1][6][7] Following a series of Soviet counter-attacks that largely stopped by April 1942, the area stabilized into stationary warfare.

[10] Following a Soviet landing in Tuloksa, which put the corps in danger of being cut off, Blick requested permission to pull back from his superior, general Paavo Talvela.

He worked as the editor-in-chief of the Kansa taisteli – miehet kertovat magazine, and held several positions of trust in organizations related to the Jäger Movement and veterans of the wars he had participated in.
