The design comprises two cupids supporting the royal coat of arms surmounted with the royal crown. The arms bear the Norman French inscription of the Order of the Garter: Honi Soit Qui Mal Y Pense. Translated this means: Shame to him who evil thinks. At the time of George III, the royal coat of arms still included the escutcheon of Hanover. This is clearly evident by the white horse and Hanoverian crown at the centre. Each cupid wears a coloured sash: the starboard figure, blue; the port figure, red. These colours indicate that the two figures represent a Seraphim (red), and a Cherubim (blue).
We know from Midshipman River's personal report of the Battle of Trafalgar that the starboard figure had its leg shot away, and the port figure, its arm.
A Seraphim, relates to the highest order of angels representing love of God.
