Storm of Kokenhusen

The Storm of Kokenhusen by the Russian Army under Tsar Alexei Mikhailovich was one of the first events of the Russo-Swedish War (1656–1658), a theater of the Second Northern War. On August 14, 1656, Russian troops stormed and captured the well-fortified town of Kokenhusen (Koknese) in Swedish Livonia (present-day Latvia)

According to the Tsar, this town “was very strong, had a deep moat, like a small brother of the Kremlin's moat, and its fortress is like a son of Smolensk's fortress”.

After capturing Kokenhusen, Russia gained control of the Daugava River and the way to Riga was opened.
