Answers.Text: No diagonal move is required: as a pawn passes through a square making a double move, any piece that guards that square could in principle capture the pawn on that square. Thus you should not exclude rook and knight from your interesting story.

  <p>You're incorrect. I've found numerous references that says that you can't capture en passant with <em>nothing</em> but pawns.</p>

  <p>From Wikipedia (<a href="https://en.wikipedia.org/wiki/En_passant">link</a>):</p>
  
  <blockquote>
    <p>It is a special pawn capture, that can only occur immediately after a pawn moves two ranks forward from its starting position, and an enemy <strong>pawn</strong> could have captured it had the pawn moved only one square forward. The opponent captures the just-moved pawn "as it passes" through the first square. The resulting position is the same as if the pawn had moved only one square forward and the enemy pawn had captured it normally.</p>

  An en passant capture is a move that involves pawns, exclusively. In particular, the king is not allowed to capture en passant.
  
  From Wikipedia ([link](https://en.wikipedia.org/wiki/En_passant)):
  
  > It is a special pawn capture, that can only occur immediately after a pawn moves two ranks forward from its starting position, and an enemy **pawn** could have captured it had the pawn moved only one square forward. The opponent captures the just-moved pawn "as it passes" through the first square. The resulting position is the same as if the pawn had moved only one square forward and the enemy pawn had captured it normally.

"Kings" and "queens" represent heavily armored "guards" troops (think bodyguards), commanded by the king and queen respectively. These are heavily armed (and armored) "formation" troops that are not good at hot pursuit. Bishops have been likened to artillery or archery, neither of which are good at chasing lightly armed peasants over broken ground. That's why only fellow pawns can use the *en passant* move.
