Commissioned in Anvers in 1814, Pacificateur remained anchored at the entrance of the harbour to protect it until the Bourbon Restoration. In September 1814, she arrived in Brest, where she stayed until she was condemned, in 1824. For her disposal, it was decided to use Pacificateur as a target ship to test new 22 cm canon-obusiers invented by Henri-Joseph Paixhans. The wooden sides of Pacificateur sustained devastating damages from the explosive shell, starting the decline of wooden warships and rise of the ironclads.
