カジミェシュ1世
In 1058 Duke Casimir I the Restorer while chasing the pagan Lithuanians and Yotvingians who devastated Polish lands, came to Sochaczew. He sent a knight of the Lis Clan ("Fox Clan") to scout the region for enemies. When the knight came across a river he met a strong enemy unit. Unable to attack them alone, he decided immediately to shoot a lighted arrow into the air to call for reinforcements. Help arrived soon and defeated the enemies. A grateful Casimir granted the brave knight a new coat of arms with an arrow in the escutcheon and his former sign - the fox - was placed in the crest.
