In 1798 he married Margarete Reck, and they had three children. During the
War of the Second Coalition against France, Bozzini served in the imperial army and was in charge of a 120-bed campaign hospital in Mainz. His extraordinary merits during this time were known by the
Archduke Karl of Austria (1771–1847), who would protect in the future Bozzini’s invention. Bozzini thought that the instrument could be incorporated into Austrian military hospitals. This required a device to be sent to Wien, and also the performance of an expertise by health authorities. An investigating committee subjected the instrument to various tests, starting with examination in corpses of the bladder, rectum, vagina, and peritoneal cavity through small laparotomies. The committee proposed some changes intended to improve the performance of the light conductor. Once such changes were made, they were satisfied with the operation of the instrument in patients (only examinations of the peritoneal cavity were not approved), particularly also because the procedure was painless. Due to intrigues in the upper governmental spheres, a second expertise was decided, this time at the Wien medical school, which performed it, and partly under the negative influence of the church, as the report turned out to be unfavorable for Bozzini and concluded that such an instrument should not be used. The second coalition war ended with the 1801
Luneville peace treaty between
Napoleon and Kaiser Franz, and the
left bank of the Rhine river remained in the hands of the French. The new Mainz government granted young Bozzini authorization to practice his profession, but he refused to accept the French citizenship and therefore decided to establish himself at Frankfurt. ==Activities in Frankfurt==
