The inscription on the foot rim reads: "TAKEN AT THE BATTLE OF COLODEN.APRL.Ye.16th.1746"
The arms are those of Knight
The initials under the base are those of Richard Knight, who is recorded in the Army List of 1746 as a soldier in the 8th Foot, a unit which took part in the Battle of Culloden. This was the last battle of the "Forty-five Rebellion," in which the Jacobites, led by Charles Edward Stuart, the Young Pretender, were defeated by the English at Culloden, near Inverness, Scotland. The grisly battle lasted only 40 minutes, and the Jacobites lost over 1,000 men, while the English lost only 50. The English army ruthlessly hunted down the remnants of Charles's army before he finally escaped to France, and final exile. The battle marked the last serious attempt of the Jacobites to restore the Stuart dynasty to the British throne.
Prince Charles's expedition started from Belleisle, not far from Rochefort in France. It is possible the beaker, which bears the hallmarks of that town, was brought over by a member of the Jacobite army, and lost during the ensuing battle. Richard Knight, a member of the English army, must have acquired the beaker after the battle and had it engraved with his arms and the inscription.
