RARE SOUVENIR OF THE SIEGE OF ACRE BY NAPOLEON BONAPARTE LARREY (Dominique-Jean). Signed "D. J. Larrey" as surgeon-in-chief of the Armée d'Orient. "Devant Acre", 25 floréal an VII [14 May 1799]. 3/4 p. in-8 oblong. Framed under glass. "The army's surgeon-in-chief certifies that C[itoy]en Jacques Boissy, lieutenant in the company of workers attached to the engineers, has an extremely serious wound which requires special care. It would be appropriate to assign this patient, who is due to be evacuated, someone who could give him the help he needs...". The Syrian campaign. Bonaparte left for Syria at the head of an expeditionary force to fight Jazzar Pasha, but the latter refused a direct confrontation, relying instead on a war of attrition and relying on the coastal strongholds: the French successively and sometimes with difficulty took El Arich (20 February 1799), Gaza (24 February), Ramlah (1 March) and Jaffa (7 March). Finally, the siege of Acre began on 19 March, but the city put up fierce resistance, with the logistical help of English and Ottoman ships, and the advice of the emigrant French soldier Antoine de Phélippeaux. Bonaparte was unable to win over the population, obtaining at best the temporary inaction of the Emir of Zaydani. In addition, he had to contend with guerrilla forces from Naples and an army from Damascus, which he defeated at the battle of Mount Tabor on 16 April. After the failure of the last two assaults on Acre on 10 May, one of which he led himself, Bonaparte lifted the siege on the night of 20-21 May, and brought back to Cairo an exhausted troop, stricken by the plague and in part defiant towards him.
