Meanwhile, the Third Army's United States Second Cavalry, a tank unit under the command of Colonel Charles Reed, had discovered the horses at Hostau, where 400 Allied prisoners of war were also being kept, and had occupied it on April 28, 1945. "Operation Cowboy", as the rescue was known, resulted in the recovery of 1,200 horses, including 375 Lipizzans. Patton learned of the raid, and arranged for Podhajsky to fly to Hostau. On May 12, American soldiers began riding, trucking, and herding the horses 35 miles across the border into Kotztinz, Germany. The Lipizzans were eventually settled in temporary quarters in Wimsbach, until the breeding stock returned to Piber in 1952, and the stallions returned to the Spanish Riding School in 1955. In 2005, the Spanish Riding School celebrated the 60th anniversary of Patton's rescue by touring the United States.
