What If?

You step out of your room. Walking down a dirt path, you pass tents carrying sick and wounded soldiers. The shouts of agony flood your senses. As you walk up to your readey troops, you feel the weight of the fallen soldiers on your shoulders. Only you can end this war. You can not fail.
"Alright listen up! This is the time you've all been ready for. The men to your left and right will be the men you fight with. We might lose some of you, but we will not fail. We will win this war! We deploy for the north tomorrow. Be ready." You tell your army.
You need to win, and to do that you'll need some extra help. But where to get it?
