Augmentation (heraldry)

In heraldry, an augmentation (often termed augmentation of honour or sometimes augmentation of arms) is a modification or addition to a coat of arms, typically given by a monarch as either a mere mark of favour, or a reward or recognition for some meritorious act. The grants of entire new coats by monarchs as a reward are not augmentations, but rather grants of arms, and (in theory) an augmentation mistakenly given to someone who did not have a right to a coat would be nugatory.

Augmentations could be of any kind: an ordinary, a charge, or a partition of the field. Most often it involves a chief or a canton, which contains a part or the entirety of the arms of the sovereign, which he concedes to a loyal vassal. Not all modifications to a coat of arms are augmentations of honour. Brisures, for example, are for the cadet lines of the dynasty, which are made by adding a label, bend, bordure, etc.

A common case of augmentations of honour are French cities having in their arms a chief Azure, three fleurs de lys or, also known as the "chief of France", given to cities "faithful" to the king.

In Scotland the most frequent augmentation is the double tressure flory counter-flory, the most recognizable part of the Scottish royal arms, although other cases can be found - for example, Sir Alexander Campbell received an augmentation "a chief argent charged with a rock proper subscribed Gibraltar, between two medals for Seringapatam and Talavera" commemorating his part in the Great Siege of Gibraltar.
