2. 1187–1189Central Europe · Holy Roman EmpireThe fall of Jerusalem spurred the Holy Roman Empire to organize the Third Crusade; German princes assembled forces and prepared field hospital units, pre-positioning manpower and supplies for the German hospital brotherhood during the siege of Acre.
3. 1190Acre · IsraelDuring the Third Crusade's siege of Acre, German crusaders from Bremen and Magdeburg set up a field hospital outside the city walls, which later developed into a permanent brotherhood hospital combining medical care with armed escort.
