Lisowczycy (; also known as
Stracency ('lost men' or '
forlorn hope') or
choragiew elearska (company of elears); or in singular form:
Lisowczyk or
elear) – the name of an early 17th-century irregular unit of the
Crown Kingdom of Poland and the
Polish–Lithuanian Commonwealth light cavalry. The Lisowczycy took part in many battles across Europe and the historical accounts of the period characterized them as extremely agile, warlike, and bloodthirsty. Their numbers varied with time, from a few hundreds to several thousands.
