Greatest and Last Victory of Polish Lithuanian Commonwealth: Battle of Oliwa. On November 28, 1627, a newly formed, relatively small Polish navy took leave from Danzig, to engage the Swedish navy in battle. The Swedish navy put a blockade on Poland's sea ports, specifically Danzig, with the objective of maintaining a stranglehold on Poland's trade routes. Poland had ten ships in operation, with a substantial number of crew, placing them in an advantageous postion over the Swedish fleet. The Polish ships flanked the Swedish flagship, the Tigern, overwhelming the Swedes and easily capturing the vessel. At the same time, the Polish vice-admiral's ship, the small galleon Meerman (Wodnik) attacked the larger Solen ("The Sun"). The captain of the Solen blew his ship up rather than allow it to be captured by the Poles. The four surviving Swedish ships retreated and headed towards the open sea and managed to escape. In the aftermath of the battle, the Polish court capitalized on the propaganda, that is, " The Sun (that is the Solen) went down at noon."
