Austro-Hungarian Empire was broken up, with Lipica becoming part of Italy. Thus, the animals were divided between several different studs in the new postwar nations of Austria, Italy, Hungary, Czechoslovakia, Romania, and Yugoslavia. The nation of Austria kept the stallions of the Spanish Riding School and some breeding stock. By 1920, the Austrian breeding stock was consolidated at Piber. During World War II, the high command of Nazi Germany transferred most of Europe's Lipizzan breeding stock to Hostau, Czechoslovakia. The breeding stock was taken from Piber in 1942, and additional mares and foals from other European nations arrived in 1943. The stallions of the Spanish Riding School were evacuated to St. Martins, Austria, from Vienna in January 1945, when bombing raids neared the city and the head of the Spanish Riding School, Colonel Alois Podhajsky, feared the horses were in danger. By spring of 1945, the horses at Hostau were threatened by the advancing Soviet army, which might have slaughtered the animals for horse meat had it captured the facility. The rescue of the Lipizzans by the United States Army, made famous by the Disney movie Miracle of the White Stallions, occurred in two parts: The Third United States Army, under the command of General George S. Patton, was near St. Martins in the spring of 1945 and learned that the Lipizzan stallions were in the area.<ref>Letts, Elizabeth. 2016.

On May 7, 1945, Podhajsky put on an exhibition of the Spanish Riding School stallions for Patton and Undersecretary of War Robert P. Patterson, and at its conclusion requested that Patton take the horses under his protection. 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
