The Crossing of the Düna (also known as Battle of Daugava or Battle of Spilves) took place during the Great Northern War on July 19, 1701 near the city of Riga, present-day Latvia. The Swedish king Charles XII was in hot pursuit of king Augustus II the Strong of the Polish–Lithuanian Commonwealth and Saxony. The crossing was easily made, and the coalition troops were quickly broken and retreated.
