I think this song is about two people who despite the fact that they are on opposite sides or political reasons should make them enemies, they still love eachother and want to be together. One is actually a member of a side, while the other is just a messenger who carries "legal documents and war plans". So they have their relationship secretly, knowing the danger, and the fact that their prospective sides are fighting eachother and if they were caught in relations they would be killed for it. Finally, the day comes when the messenger is carrying plans for the base where his lover is stationed to be attacked and destroyed, he risks his life to go and warn her, but the window won't open and he can't get in and she can't see him. He can't save her after all and her base is attacked and destroyed/burned, and he watches it all happen, helplessly.
