Valuable sources for establishing the scope and chronology of the Tatar invasion of Prussia in 1656 are records of damage and prisoners taken by the horde. So far, 4 such documents have been known and published, concerning the mayorship of Elec, the mayorship of Polom, the mayors of Piskie and Rhin. The last two were drawn up in 1663 and are in fact named lists of Tatar jasyr. Published in the article, the list of damages caused by the Tatar invasion on the territory of the Riga mayor is a source for hitherto unknown historians, at the same time the earliest of its type document, and also contains new data. It is housed in the Geheimes Staatarchiv Prussian Kulturbesitz Berlin-Dahlem.Source text in German
