The SS Gebirgs Pioneer Battalion 13 was based in Villefranche de Rovergue capital of an arrondissement in the region of Aveyron near Lyon, only since August 6, 1943. Some 200 Bosnian were brought to the town and placed in a German training camp. During September 17-18, four division recruits, including two officer cadets - their names were Ferid Dzanic, Nikola Vukelic, Eduard Matutinovic (alias Bozidar Bozo Jelenek, alias Leopold), and Lutfija Dizdarevic - from the battalion, persuade their compatriots to support them to mutiny against their German officers. Their goal was to approach French liberation movement and Anglo-America, and then to come back to their homeland.
A high-school ground that became barrack for SS Gebirgs Pioneer Battalion 13.
Initially, they succeed to get support from a number of soldiers for their cause. On the night of September 16th, the mutiny was begun. The mutineers executed five German officers, held many others Germans, and successful establishing control over entire garrison. By 08:00 a.m. they controlled the entire town.
When the news about the mutiny was hear by the German Command, they were quickly brought in reinforcements and begun the siege of the town. Heavy fighting lasted until 20:00 p.m. Meanwhile, a division imam, Waffen-Obersturmführer der SS Halim Malkoc, convinces the rank and file troops to German side. The mutiny fizzles out and loyal Bosnian and a few Germans who had managed to evade the mutineers put it down. Two of the mutineers were killed. One captured. Only five or six mutineers managed to escape, including Eduard Matutinovic, with helped by the French people and join the French Resistance.
Although what happened in Villefranche de Rovergue was a mutiny, the fact was that only very few soldiers participated in the uprising. From the investigation after the incident, the fault of the mutiny could be squarely placed on the communists who had planted by Tito within the division as a means of disrupting training and recruitment, and a handful of malcontents. Not only did a great majority of the troops not participate in the mutiny, but also most either had no idea it was happening or actively help to quash it.
Himmler was furious at his officers had treated the Bosnian but had no choice but to shoot the mutineers. The SS then purged the division. Fourteen mutineers were shot; 825 unreliable men were shipped to Germany and informed that they were to volunteer for the labor service or not be fed. Some 536 men volunteered for the Organization Todt and were sent to labor gangs working on the Siegfried Line; but 265 holdouts were sent to the concentration camp at Neuengamme where few, if any, survived the war.
The SS believed that the French population had somehow abetted the mutiny. A part of their suspicion was true because the courageous people of Villefranche de Rovergue did not only help the mutineers but also hiding some of them, waiting the time join the French Resistance, after the failed uprising.
This rebellion itself, the first within the Nazi military system during the World War II, was highly esteemed by the French citizens of Villefranche-de-Rouergue. The French witnesses called this insurrection la révolte des Croates. According to Louis Erignac, Villefranche-de-Rouergue was the first free city of occupied France. So, when the city was liberated in 1944, they decided to pay tribute to these tragic victims by naming one of its streets as Avenue des Croates to honor the graves of the brave soldiers they called les Croates. [Even today citizens of the city regularly commemorate this tragic event (September 14th). In 1952 the participants of the Croatian Partisan Movement planned to build up a memorial to the Croatian victims in Villefranche-de-Rouergue (with a sculpture of Vanja Radaus), but this has been prevented by the (ex) Yugoslav government in Belgrade under the pretext that in this way the "quislings" would be honored. So the only thing that existed to remember them is a wooden sign hidden by the trees blossoming reads champs des martyrs yougoslaves (Field of the Yugoslavian Martyrs) at the entrance of the field where the martyrs were executed].
To stiffen the resolve of the Bosnian volunteers, the division was sent to the more Germanic environment of Neuhammer in Silesia, Germany. Departures for the Neuhammer training area began on October 1. To restore the order in the division, Himmler sent the Grand Mufti to use his religious charisma.
