I cannot understand the word "Heeressache" rubber stamped on a cover sent from From Der Territorialdelegierte der freiwilligen Krankenpflege für das Großherzogtum Sachsen. (The Territorial Delegate for Volunteer Nursing of the Grand Duchy of Saxony.) To Das Centralkimitee der Deutsches Verine vom Roten Kreuz. (The Central Committee of the German Union of the Red Cross.)
