Scale: approximately 1:120. A full hull model of a French 110-gun three-decker ship of the line. The model is decked, equipped and rigged. Unusually for a prisoner of war model, it is made of wood, rather than bone. It is to a relatively large scale for such models, though as usual the details tend to be more accurate than the shape of the hull, as the modellers were not able to work from plans. It shows boats being lowered over the side and stern, with fine though not very accurate detail of some of the deck fittings, and figures of seamen.

The name ‘Impregnable’ is painted on the stern, though this model represents a ship much larger than the real ships of 1780 and 1810 that bore the name. Prisoner of war modellers tended to exaggerate features of the ship, including the number of guns.

The French introduced the 120-gun ship late in the 18th century as a development of the 100-gun ship. The first British one was the ‘Caledonia’, launched in 1808.
