The army assembled in a complicated battle formation. With so many soldiers, it was vast and unwieldy, and mostly useless… but not entirely so.
The Masters and the Saints were going to assault the vermilion jungle, but the Awakened were prepared to fight, as well.
Obviously, they had very little chance of killing Corrupted abominations, not to mention the Great horrors who dwelled in Godgrave. However, they did not necessarily need to.
The commanders of the Song Army were well aware of the limitations facing their troops, so they had come up with various chilling, but effective strategies. If it came to that, the task of the Awakened soldiers was not to kill the powerful abominations, but to immobilize them.
Although hard, that could be achieved with numbers alone. Even if an abomination had to be buried in human bodies, that was one way to deal with it.
