Dominican friar Simon Okolski (1580 – 1653) accompanied Hetman M.Potocki in campaigns against the Cossacks in 1637 and 1638. During the campaign he kept a diary, which was published in 1638 (the 1637 campaign) and 1639 (the 1638 campaign), respectively. These diaries are a valuable source and is actively used by later historians, including S.Velychko and S.Lukomsky. In 1858 they were reprinted [Okolski S. Dyariusz transakcji wojennej miedzy wojskom koronnym i zaporoskim w r.1637, tudzież Kontynuacya diariusza wojennego w roku 1638. – Kraków: 1858].
