Stepping into a ---field here- but I'm basing the song on what I have actually been told by those I've spoken to, bearing in mind that they are relatives of those who were there, and the oral history, tryingto get their words into a song. Long time ago wrote a song about mercenaries in Angola based on info which proved to be utterly false ( wrote a song about writing that song too...) which cured this writer of basing songs on newspaper/TV. Where the truth rests depends on the point of view- and these are real people we're talking about, not pawns.
