So I was just watching Troy, and was wondering what the siege of Troy would have been like if Achilles had been convinced to go with the Greeks. I kniw he's a minor character, and yes, the film is not the best adaptation of The Hektoriad [OOC: I know that isn't right, but i couldn't find the proper genitive form of Hector in either Greek or Latin.], but supposedly he was the greatest warrior in Greece, blessed by the gods to be unkillable in battle. Would the Greeks have been able to break the siege with an invulnerable warrior at the lead?
