Alan Devonshire has blamed ref Nigel Lugg for stoking the fire that erupted in four players being sent off in one flashpoint incident on Saturday.
The dismissals, two from Hampton & Richmond and two from home team Havant & Waterlooville, scarred an otherwise outstanding 4-1 victory for the Beavers over the Blue Square South's pre-season favourites.
In all, Lugg handed Hampton six bookings and one straight red, while Havant received two reds.
Beavers boss Dev said: "I think the referee got things wrong from the start.
"We were on the end of some really heavy tackles that went unpunished, and then he booked one of ours for his first mistimed challenge.
"It went on like that, and the players were clearly getting very frustrated.
"The big bust-up started when Craig Watkins lunged in on Robbie Kember, who suffered stud marks on the top of his things.
"Kember got up and retaliated, and then all hell broke loose. I was about 50 yards away so I did not see everything, but when the dust settled Kember got a second yellow for retaliation and Orlando Jeffrey got a red for shoving an opponent.
"There will be club fines for both our players, who will miss the league match against Fisher on Saturday week.
The dismissals seemed to affect Havant much more than Hampton, whose win pushed them up to seventh place.
Dev said: "It is a shame that this game will be remembered for four men going off rather than the excellent football we played against really tough opposition, who had won at Chelmsford the previous week."
Ben Wright, starting as Lawrence Yaku was feeling a thigh strain, opened the scoring with a 25-yard screamer.
Dev said: "He is just 19, and certainly one for the future."
Hampton's other goals came from Ian Hodges, John Scarborough and Ryan Lake.
Devonshire hopes to have Yaku, Stuart Lake and Nana Badu back from injury for Saturday's FA Cup second qualifying round match at Dartford.
Dev added: "They beat Horsham 4-0 on Saturday and will be a really tough nut to crack."
Meanwhile, Hampton's reserves beat Horley Town 3-0 in the Suburban League Cup.
* HAVING failed to score all season, Richard Butler got off the mark with three goals in two games for Staines Town in the Ryman Premier this week.
Butler opened his account for the campaign as Staines drew 1-1 at Ramsgate on Saturday, then bagged a brace in Tuesday night's 2-1 win over Hendon.
Last season's FA Cup giant-killers host Hayes & Yeading in the second qualifying round on Saturday.
Meanwhile, Butler's former club, Ashford Town (Middx), could have done with some of his goal-power this week as their slide continued.
The early-season Ryman Premier leaders crashed 1-0 at home to Margate on Saturday, then went down by the same scoreline at Carshalton on Tuesday night - their fourth successive defeat.
They will hope to bounce back when they visit Arlesley Town in the FA Cup on Saturday.
