The siege of Wesenberg, Rakvere, or Rakovor, was an abortive Swedish siege of the Russian-held town of Wesenberg in Estonia from January through March 1574, during the Livonian War. The siege is infamous for a brawl and subsequent combat between German and Scottish mercenaries within the besieging army, which claimed the lives of about 1,500 Scots. Wesenberg was seized in a renewed Swedish assault in 1581.
