Looks like that whole story about Ukrainian soldiers saying fuck you to a Russian warship and fighting to the death was likely staged for propaganda purposes; Another fake.
Russia has said there were no casualties and has been releasing videos of their military taking a large number of Ukrainian soldiers prisoner on the island that was supposedly bombed.

Time will tell which version of the story is true, but I can find no evidence to suggest the Ukrainian president, Zelensky and his comrades are telling the truth.
From the original Guardian article that was posted here: "The audio has been published by multiple media outlets including the Ukrainian
online newspaper Ukrayinska Pravda"
This is a Babylon Bee type story; They actually cited an online newspaper called "Pravda" (The name of the infamous Soviet Bolshevik propaganda newspaper) to release this story.
