The Thirteen Ukrainian border guards stationed on Snake Island that were initially reported by the Ukrainian president to have been killed in action, have now been confirmed as captured by Russian forces.

The thirteen soldiers immediately set the tone for the war and rallied support for Ukraine after telling an approaching Russian warship to "Go f*ck yourself".

According to a post shared to the Ukrainian Navy's official Facebook page on Monday, officials said, per a translation: "The Marines and frontier guards captured by the Russian occupiers on Snake Island are alive and well!"

Russian state media also showed the arrival of the Ukrainian soldiers in Sevastopol, Crimea where they are currently being held.

Snake Island, also known as Zmiinyi Island, sits about 30 miles (48 kilometers) off the southern tip of the Ukrainian mainland in the northwestern Black Sea. It’s about 185 miles west of Crimea, the Ukrainian territory that Russia annexed in 2014.
