The Croats were initially recruited by generals of the Habsburg Monarchy. The soldiers who joined Croats signed contracts which expired after the military campaign would be over, most often for any booty and sometimes for a fee. At the beginning, their bands were loosely organized. They were dismissed after the military campaign was finished and returned in the spring to be recruited by their old commanders. In 1623 the size of the Croat units under command of Count of Tilly was reduced from 172 hearths to 72. They participated in the 1623 Battle of Stadtlohn under Tilly's command.
Establishment of the regular units
The first regular Croat regiment was established in 1625 by Hector Ludwig Isolani, a military officerin service of Albrecht von Wallenstein. Most commanders of the Croats were Hungarians. The duties of the Croats were mostly out of the battlefield because they did not have significant combat value. In rare cases when they participated in the battle, they were engaged to confuse the enemy flanks by attacking their wings. In many historical works the Croats are criticized for their cruel methods. It has been reported that the worst atrocities during the Sack of Magdeburg were committed by the Croats and Walloons. By the end of 1633 the Croats began their service in the army of the Kingdom of France.
Equipment and uniform
The Croats wore hats made of fur and long red cloaks. Their primary arms were carbines. Besides carbine the Croat arms included two pistols. The Croats wore scarves around their necks, probably for hygienic purposes. During the Thirty Years' War the Croats came in contact with French who were impressed by their outfit and soon adopted the scarf, naming it after the Croats which evolved into the modern-day cravat and necktie. The Cravat Regiment is a guard of honour established in 2010 in Zagreb, Croatia, which wears uniforms that are replicas of those worn by the Croats.
Legacy
The influence of the Croat military unit was so strong that between 1631 and 1638 similar units were established in Bavaria, Spain and France. At the beginning of the 20th century mothers still scared their children with tales about the 1631 Sack of Magdeburg in which Croats took part. The population of eastern France compared all invasions after the Thirty Years' War with stories about Croats and Swedes who ravaged their territory in the 1630s. The Croats are mentioned in Grimmelshausen's Simplicissimus and in Friedrich Schiller's Wallenstein.
