Was the St Valentine's Day Massacre successful?

Answer:
No, in that George "Bug" Moran was not eliminated and he was the planned target. Moran elected to end his competition with the South Side Gang under Al Capone and they effectively became the Chicago Gang, The Mob or the Outfit.
Moran eventually died a pauper at Fort Leavenworth Federal Pennitentiary in Leavenworth, Kansas at the age of 65 where he was serving time for bank robbery.
