This song is about A soldier who goes to a war zone and leaving his girlfriend behind.
In the beginning of this song, He was about to board the ship which was getting ready to sail the next day. He misses his girlfriend. I think she must be beautiful indeed because he quoted that many times in this song.
What I assume from the lyrics is, he must have been to the war zone before. Because he said that he knew the taste of War. So he met her after serving in the army for a certain period. That’s why he couldn’t leave her just like that. He felt that the farewell was more painful than the war.
He said, “It brings no sorrow” which means he might die on the battlefield, but he didn’t care because he won’t be alive to feel the pain. But this exact farewell moment was killing him. That’s why he couldn’t leave her just like that. He felt that the farewell was more painful than the war.
He was thinking about her during the battle while enemy’s guns were firing at his troop. But he hoped that he would return to his home after all these agonies.
