Unfortunately, Le Jeune was found out to be the author of an anti-Catholic tract in 1589, and was forced to flee Paris during the siege that year: only the intervention of his friend, the composer Jacques Mauduit, at the city's St. Denis gate saved his life and prevented the destruction of the manuscripts he carried with him (according to Marin Mersenne, who wrote extensively about both composers in his "Harmonie universelle" of 1637). Other Huguenot composers were not so fortunate. Claude Goudimel, a very similar composer whom Le Jeune may have known, was murdered by a Catholic mob in Lyon during the St. Bartholomew's Day massacre in late August 1572.
