A couple of points regarding English usage:

"The latest of the fall" doesn't sound right. "Fall" is more American usage than English (we'd usually say "Autumn") but you could certainly get away with it. However, the whole phrase is a give-away that you're not a native speaker. I can offer "As Autumn leaves began to fall/Then from our army came the call" as an alternative.

You wouldn't say "enquired to". The correct usage would be "enquired of", but this is a bit formal and in ordinary speech you'd probably just say "enquired".

Similarly, you wouldn't say "fought beside of you", simply "beside you". "Alongside you" would also work, if you want to retain the three syllables.

These are details, though. Taken as a whole, it's a good song and your grasp of English is impressive.
