Crossing the Delamare

For centuries, the ponies of Equestria have disputed and fought. After an argument over whether eggs are best done sunny-side-up or over-easy turned hostile, the first pony war between the Unicorns, the Pegasi and the Earth Ponies began. Although talks on all sides were made, their leaders: Princess Platinum, Commander Hurricane and Chancellor Puddinghead left to find new lands. During this time, the Apples seized the initiative against their unicorn neighbours, the Oranges, and crossed the Delamare during the night (or at least what could be considered night during an eternal winter). Unfortunately, half way through the crossing, Castle Orange discovered them and began a cannon assault! Will the apples make it?
