Colorado has a special tie to the liberation. The 157th Infantry Regiment, 45th Division, was formed from a Colorado National Guard unit. Those soldiers helped free prisoners at Dachau, one of the most infamous concentration camps.

Sunday’s remembrance took place at the Hebrew Educational Alliance in Denver.
