As early as 1837, he insisted on the double experience necessary for a military surgeon: at the same time on the battlefield then in hospital. He was a defender of early amputations, accomplished with a true parage of regularization, the most distal possible to keep length and flaps suffisant for future equipment. It is a current recommendation for the realization of amputations in war traumatology and which is necessary for a functional equipment. In 1853, in the
French Academy of Sciences, he laid out the basic principles and rules of conduct that ensure good use of chloroform and considered this drug as the most effective and successful in military surgery. He was sent on mission as expert during the
Crimean War in 1855 by Marshal
Vaillant. His mission was to inspect Army medical services and to report on the condition of military hospitals and ambulances. On site, he helped wounded and ill soldiers by taking forward measures against Service Corps and separated wounded and soldiers suffering from typhus. He was impressed by the work of the
Daughters of Charity of Saint Vincent de Paul, of the Russian Sisters of the Exaltation of the Cross and specially of
Florence Nightingale. He reported that chloroform had been successfully used in more than 25,000 wounded (over 8% of the total force). Himself fell ill with typhus and back in Paris, he died on 27 December 1857, aged 53. ==Works==
