Hypothetical scenario: What if the war of the ring started before Smaug destroyed Dale and Erebor? Sauron feels he has enough troops to launch a assault on Gondor. He starts his invasion of Gondor with Osgiliath. Beregond, the steward at that time send emisarries to all realms in Middle-Earth for help. All responds yes and sends their forces to Minas Tirith. Could the combined armies of Gondor, Rohan, Dale, Erebor, Rivendell, Lorien, Woodland Realm and Dol Amroth push back Sauron and eventually destroy his army completely? Assuming Sauron has the same strength as during the real War of the Ring.
