From the very beginning of its existence, the Baltic Fleet has had a huge influence on the victories of the Russian army. During the Northern War, with the support of sailors, a number of cities were taken and several major naval victories were won. The day of the holiday - May 18 - was chosen for a reason. On this day, Peter I captured the Swedish boat and shnyava on thirty boats. The very fact of the Russian victory at sea, where the Europeans had no equal, turned out to be important.
