This song is about a girl who just turned eighteen and got married after two weeks. She was going to a funeral of her dead husband who's a soldier. She's wearing a white dress but not a wedding dress (some people wear white, aside from black, in mourning) the veil is not a wedding veil, too. She knew that her husband is dead already but couldn't accept the truth. And the flowers are really for his husband's death. The first stanza is quite tricky coz we might think that it's a wedding ceremony but honestly, if you'll focus in the story. It's a funeral not a wedding at all.
