 Napoleon's attempt to install the archduke Maximilian, the brother of the Austrian Emperor, in Mexico was just coming to its disastrous conclusion; the French troops had just been withdrawn from Mexico in February 1867, and the unfortunate Maximilian would be captured, judged and shot by a firing squad on 19 June.Napoleon III made these offers again in August 1867, on a visit to offer condolences for the death of Maximilian, but the proposal was not received with enthusiasm.Napoleon III also made one last attempt to persuade Italy to be his ally against Prussia.
