I see
Apparently, [I] is able to sent 3 ships from 1 jumpgate in to my planets that has +3 defense and the battle actually took place.
He destroyed all my structure as a result
This has happened to 3 of my planet
None of the 3 planet is adjacent to any [I] planet so he can only sent ships via jumpgate, all 3 planet has +3 defense
