You saved your girls by acting quickly.
I know, I was charged by a raccoon in my backyard that was raiding my next door neighbor's trash. I heard the noise and went out there to investigate. Darn thing leaped off the fence, hissing and growling at me while giving chase. I was very lucky I was only steps from the backdoor- was able to get a glimpse at the raccoon before slamming the door shut. I now use a flashlight making sure no eyes are reflecting back at me before I step out into the yard at night.
This is a video of a man saving his dog from a raccoon attack.
