To deal with a horde of guards in an open space, you have to be able to circle around them, picking them off one or two at a time.
I find it's easier to have your sword on a diagonal and to turn it as little as possible. If some guards are turning instead of moving, that'll separate them a little.
Here's a possible start:

×Start on the east side, with your sword facing NE.
Go North 6, until you are just inside the main area with the corner to your SE.
Head NE until there's a sword in your way.
N then SE will kill two guards.
SW SW N, SW SW N will kill two more guards.
