Everything I have seen indicates the Arcuri's were part of original onslaught against the Rizzuto's, However it seems like Arcuri's also supported Montagna against Di Maulo/De Vito and Desjardins.

It doesn't seem like Arcuri/Montagna had many people backing them once they broke from the Devito/Di Maulo/Desjardins group. Possibly Pietrantonio and Lopresti but most of what I have seen indicates they were still representing Rizzuto or possibly Cu-ntrera interests. Arcuri hasn't been seen in Montreal since August now while all of the other major players from the other sides are in Montreal fighting for Territory.

I think the body count is now higher on those who opposed the Rizzuto's. I could be wrong on this but I don't think the Rizzuto side have taken any major hits in almost 2 years now .
