The wizards can't beat the Army of the dead (No one can), but they can easily escape.
So they hide... Yep, still a loss in my book.

The food was already made and prepared by the House Elves. Dumbledore didn't really make the food appear out of thin air , but made it "teleport" for lack of a better word.
