The city fell on 15 May 1867 and Maximilian was captured the next morning after the failure of an attempt to escape through Republican lines by a loyal hussar cavalry brigade led by Felix Salm-Salm. Following a court-martial, he was sentenced to death. Many of the crowned heads of Europe and other prominent figures (including the eminent liberals Victor Hugo and Giuseppe Garibaldi) sent telegrams and letters to Mexico pleading desperately for the Emperor's life to be spared. Although he liked Maximilian on a personal level,[39] Juárez refused to commute the sentence in view of the Mexicans who had been killed fighting against Maximilian's forces, and because he believed it was necessary to send a message that Mexico would not tolerate any government imposed by foreign powers. Felix Salm-Salm and his wife masterminded a plan and bribed the jailors to allow Maximilian to escape execution. However, Maximilian would not go through with the plan because he felt that shaving his beard to avoid recognition would ruin his dignity if he were to be recaptured.[40] The sentence was carried out in the Cerro de las Campanas on the morning of 19 June 1867, when Maximilian, along with Generals Miramón and Mejía, were executed by a firing squad. He spoke only in Spanish and gave his executioners a portion of gold not to shoot him in the head so that his mother could see his face. His last words were, "I forgive everyone, and I ask everyone to forgive me. May my blood, which is about to be shed, be for the good of the country. Viva Mexico, viva la independencia!"[41] Generals Miramón and Mejía were shot after him. Both died shouting, "Long live the Emperor."
