French soldiers crossed the Rhine and arrested the Duke in his own house at Ettenheim. They arrived with him at Paris on the 20th. He was taken to the fort of Vincennes without entering the city.

Austria kept silent, but watched the signs of coming war. France alone showed no pity. Before the Duke of Enghien had been dead a week, the Senate besought Napoleon to give to France the security of a hereditary throne. Prefects, bishops, mayors, and councils with one voice repeated the official prayer. A resolution in favour of imperial rule was brought forward in the Tribunate, and passed, after a noble and solitary protest on the part of Carnot.
