"THE REGIMENTAL ARTILLERY
In 1811 each infantry regiment received two ex-Austrian 3pdr light field pieces and the regiment received authority to raise a company of forty men to form a regimental train to be responsible for the movement of the cannon, caissons, forges and ambulances for the unit. The personnel were to be found from the battalion strength. Officers and NCOs wore the regimental uniform.
The Regimental Artillery were not part of the Artillery Corps, but were an integral part of the infantry regiment and their uniforms reflected that status. The Majster-Kanonier wore the infantry style czapka as for the grenadier company with scarlet pompon, cords and flounders. The front plate may have been embossed with either a grenade or the crossed cannon motif. The Kanonier wore the same czapka but with a black pompon.
Coats were a dark blue kurtka with black collar, cuffs, cuff-flaps and turnbacks all piped scarlet and the Majster-Kanonier wore full fringed scarlet epaulettes. The Kanonier wore plain dark blue shoulder-straps as for the fusiliers with scarlet piping. All buttons were brass. In 1812 the Kanoniers appear to have been re-uniformed in a dark blue habit a la Kinski with facings as previously prior to the Russian campaign. [21]
The Legwear for the Majster-Kanonier was as for the regiments, with white overall trousers worn for campaign. The Kanoniers who were also drivers for the battery wore heavy cloth dark grey overalls with black leather cuffs and inserts.
Equipment was as for the infantry elite companies, and sabre-straps were scarlet. The Kanonier wore a single shoulder belt which supported a sabre briquet only, with white sabre-strap.
NOTES:
[21] The Regiment of Foot Artillery and two companies of Horse Artillery formed from the survivors of the 1812 campaign in Russia received new uniforms in 1813. Both wore a French style shako with white cockade, yellow cockade-strap and scarlet plume and cords. The coat was the habit a la Kinski with collar, cuffs and turnbacks black piped scarlet and all buttons brass. Epaulettes and aiguillettes were scarlet for both foot and horse companies. Conflicting accounts have this coat as the normal dark green or dark blue in 1813 but the change of colour to dark blue has not been confirmed at the time of writing although it is shown by Pouvesle. It is possible that this may be confused with the 1812 orders for the uniforms for Regimental Artillery. Other details remained as previously."
