Among the papers of Mikael von Strokirch, Economy Governor in the Latvian district of Livonia, there is a specification of a suitable model of uniform for the militia. It is undated, but appears to be from June 1702:
A grey vadmal coat with yellow lining, grey karpus with yellow lining, leather breeches (if possible, otherwise one pair of vadmal and one pair of linen), woolen socks and gloves, leather shoes, a pair of shirts, a pair of linen neckcloths, a short fur coat for the winter, cartridge box in two parts (of black leather) and a leather belt.
In a following letter to a captain in the militia Strokirch states that the recently departed Governor General Dahlbergh had not made any decision regarding how the militia was to be dressed, he had simply approved the suggestions made by various captains. The result had been something like the enclosed specification.
