You might want to substitute "troops" or "Orkish regiments" for "armies" in the second verse, as there were actually only two armies arrayed against Men during the WotR---Sauron's and Saruman's. Other than that, fine job.
Author's Response: 'Armies' is implied here as a large group of 'people' gathered to fight a purpose. Even if this 'purpose' is a 'stupid' one. But as always, thank you for your review! -Midnight §
