I’m looking for information on mainly the campaign uniforms/equipment / schabraque etc for this unit campaigning in Russia and in Germany.
Have tried the History Bookman's Site?
You can get a pdf of his "The Army of the Grand Duchy of Berg" it is 77 pages long for £5
In the original equipment of 1807 the shabraques were amaranth. These were changed to the usual light cavalry usage of sheepskin covers to the saddle in place of a cloth shabraque.
Apparently, but I cannot be sure of it, the lances were probably left a natural wood color. In the illustrations that I have they are brown.
The Lancers of Berg were formed originally in 1807 as one regiment of light cavalry (chevaulegers) without lances. The original uniform was a striking white lancer uniform complete with czapka with crimson (amaranth) facings and trousers. This uniform was similar to the proposed, but never issued, full dress of the Guard's 1st Lancer Regiment.
The first uniform was worn by the two squadrons of the regiment that accompanied Murat into Spain in 1808.
The above uniform was too expensive, so the regiment was reuniformed in a green chasseur a cheval-type uniform, the line companies in a shako and the elite company in a colpack. The facings, and the shakos were rose. The regiment was rearmed and trained as lancers and accompanied the provisional Guard division into Spain in 1809.
This was the uniform in 1812 apparently. In 1813 the headgear was again the tsapka and a more complete lancer-type uniform, still green with rose facings, though the 'official' color was crimson. The regiment established an excellent record in Spain against both regular units and guerillas and was awarded the distinction of silk lance pennons like the 1st Polish Lancer Regiment of the Guard.'
A 2d Regiment was formed in 1813, the two units becoming the Berg Brigade, the 1st Regiment being recalled from Spain. The personnel were Germans and the unit served with the Guard. However, the unit was associated with the Guard but not actually officially part of it. When the French retreated from Germany, the unit became unreliable and was dismounted and disarmed.
Epaulets were apparently white, the top of the tsapkas were rose. In 1813 the trumpeters wore the Imperial livery.
