Questions about the Heroes 4 map editor.

Hello! I'm too lazy to reread all the pages, so I apologize if a similar question has already been asked. Imagine this situation: There is a purple ship. How can I destroy it using scripts (triggers)? I mean not only the crew but the ship itself. I've tried the following options: 1) Battle with an invincible enemy. The ship remains empty. 2) Changing the ship to "No player" (gray color) -> Battle with an invincible enemy. The ship remains empty and gray. Options involving dynamite (I don't know if it's possible) and changing a neighboring ship to an enemy color are not acceptable. I would be very grateful for your help. I will reward you with a campaign.
