Animate Horde

You flood a 1,000 foot radius sphere centered on yourself with necromantic energy. Your spell imbues all corpses and bone piles within the area with a foul mimicry of life, raising it as an Undead creature. Each target becomes a Skeleton if it's bones or a Zombie if it's a corpse (the DM has the creature's game statistics).

On each of your turns, you can use a Bonus Action to mentally command any creature you made with this spell if the creature is within 60 feet of you (if you control multiple creatures, you can command any or all of them at the same time, issuing the same command to each one). You decide what action the creature will take and where it will move during its next turn, or you can issue a general command, such as to guard a particular Chamber or corridor. If you issue no commands, the creature only defends itself against Hostile creatures. Once given an order, the creature continues to follow it until its task is complete.
