In the summer of 1701, during the Northern War, a battle was fought near Riga between the Swedish armies and the Saxons. Tsar Peter I sent a detachment of Russian troops to the aid of his Saxon allies. In their retreat, the Saxons forgot about their allies stationed on the island of Lucavsala. Around 400 Russian soldiers perished in the uneven battle. In 1891 a memorial to the Russian soldiers was erected on the island.
