Jasper Theodore Aaser, born 9 Jul 1917, was the middle of five sons of Ole Petterson Aaser and Marie (Franson) Aaser of Hamlin Township, Nelson County, North Dakota. In the 1940 census 22-year-old Jasper is living with his parents and brothers Orvin 27, Morris 24, Joseph 22, Martin 10, and Elwood 9, still in Hamlin Township. His father is a farmer and Orvin, Morris and Jasper are all working the family farm. Staff Sergeant Aaser was in the 359th Infantry Regiment of the 90th Infantry Division. On 10 Jan 1945, the 359th IR was north of the Sure River in Luxembourg 10 miles east southeast of Bastogne, Belgium. The 90th was in place, ready to assault the enemy east of Bastogne, but it found the weather definitely pro-nazi. On the icy grades, trucks skidded and plunged into ditches. Tanks spun their tracks helplessly and high winds, sweeping down the valleys and across the ridges, drifted the snow into cuts along the roads. The NARA WWII casualty listings by state and county show that Aaser, Jasper T., 37172273, S Sgt, from Nelson County, North Dakota, was killed in action that day on 10 January 1945.
