La Gloire combined a wooden hull with iron armour and was tested against the powerful guns of its day at a distance intended to reproduce extremely close combat. The discussion cautions against treating her appearance as an immediate rendering of all unarmoured ships obsolete: many wooden steam ships could still outrun her. Her changing armament also shows that the first ironclad generation remained subject to rapid experimentation after completion. Her value lies in showing how armour, propulsion, guns, and speed had to be balanced together rather than treated as a single revolutionary switch.
