- On April 12, 2022, Ukrposhta put into circulation postage stamps "Russian warship, go...!", which artistically depicted the first days of Russia's military aggression against Ukraine and one of the bright pages of the resistance to the Ukrainian military occupier - the response of the defenders of the Snake Island to the Russian cruiser "Moskva" on the offer to surrender. The very next day after the introduction of stamps into circulation - April 13 - it became known about the successful operation of the Armed Forces of Ukraine, as a result of which the flagship of the Black Sea Fleet of Russia was hit and sank on April 14, 2022.
