I know how i'd have reacted. First chance to run and i'd take it. Boxed in, outnumbered, bigger, younger, fired up attackers. If i felt that aggrieved i'd seek to resolve the situation at a time and place of my choosing and when i'd assembled a bit of back up. Very much doubt i'd bother though, chalk it down to experience. The best way to win a fight is not to have it, triumphs over revenge being a dish best served cold for me i think. That said if it was my close rels (eg kids/parents) who'd been targetted by those cunts, i think i'd want to smash the cowardly fuckers square in the face!
