Hmm, hoom etc.

Not such an easy one Legate....


Maybe this is the answer, probably not! Still eliminates a possibility even so.

Before the Black King made his move --- before Siege of Gondor
after the White Queen's done her due --- Galadriel, Lothlorien
our Rook is threatened, gone our Knight --- Helm's Deep, Theodred dead
and it is White against the White --- White Hand v White Horse

Now it's my turn, with no delay --- Ceorl
I will just move, then I will say, --- a horseman riding back towards them
me, lonely Pawn, the tale of loss. --- of the Fords of the Isen
So many of the other Pawns --- Orcs, Halforcs Dunlendings and Goblin Men
have taken our Knight en passant --- what has become of Erkenbrand none seem to know
I thought our figures are all gone... --- the rest are scattered

But I see King, now moves a Knight - --- Theoden, Gandalf rides off
will it be White against the White? --- Gandalf v Saruman?

I don't think a pawn can't take a knight en passant? Indeed Erkenbrand survived to save the day. OK I'm stretching this one huh?
