The Ukrainian Navy has confirmed that the garrison of Snake Island in the Black Sea off the coast of Ukraine is alive and was captured by Russian naval forces.

SOFREP was among other media outlets that reported on Ukrainian claims that 13 members of the garrison had been killed after being hailed by a Russian warship that demanded that they lay down their arms and surrender without a fight.

The Ukrainian government provided an audio recording and transcript of the Russian Navy ship cruising close to the island and using a loudspeaker to call out to the island’s defenders on February 24th.

“This is a Russian warship,” according to the transcript by Reuters News. “I propose you lay down your weapons and surrender to avoid bloodshed and unnecessary victims. Otherwise, you will be bombed.”
