WGC lost only their third league game this season, as hosts Broxbourne Boro joined Codicote and Southall as the only sides in SSML Div 1 to lower the Citizens' colours this season.
And in truth, Adam Fisher's side could have little complaint in losing this one.
A fiercely competitive and pumped-up Broxbourne were the better side, certainly in the first-half, of a game which saw referee Matthew Ball hand out two red cards - one to WGC's Jack Dekanski in stoppage time that will mean a five match ban.
It was Dekanski's, who was sent off for being last man, rather than the severity of the challenge, third red card of the current campaign and will see him miss five of the Citizens' eight remaining league fixtures.
It will also be a game that WGC's normally very reliable keeper Joe Croft won't want to remember either, as it was his 78th minute gaffe that handed Broxbourne the points, when he came for and fumbled a left-wing free-kick, that home defender Sean Flaherty forced over the line, in the ensuing goalline scramble.
WGC were fortunate to be on level terms at the interval, Croft having made two fine trademark dashes from his line to snatch the ball off the toes of Broxbourne's Adam Murad and top scorer Bradley Harrison in the opening 15 minutes.
Then when Harrison met a right-wing corner with a powerful, on-target header, WGC were grateful to a fine goalline clearance from full-back Jay Lovell to preserve the parity.
The Citizens had few chances and no real openings until the 37th minute, when Jason Caswell rescued a pass on the left by-line, switched passes with Joel Norris who played him clean through, but Caswell couldn't lift his effort over keeper Olajaid, who saved at his feet.
Murad closed the half with a powerful effort for the home side that was just inches wide.
WGC began the second-half in much livelier fashion and two minutes in, missed a glorious chance to take the lead.
Norris made a fine run behind the home defence and centred across the face of goal, but just when Marc Arnott looked as though he must score, he got the ball tangled between his legs almost on the goalline and the chance was lost!
Croft pulled off a fine tip-over save when Harrison got the better of Dekanski to meet a left-wing cross, before WGC took a somewhat undeserved lead in 52 minutes.
A Sean Brettell corner was pulled out to the edge of the box and chipped forward for Yasin Boodhoo, playing in midfield in this game, to toe-poke past the keeper as he came out.
The lead lasted 10 minutes before a Broxbourne free-kick out on the left, forced Croft into another fingertip save onto the crossbar, but when this one fell to ground, the predatory Harrison bundled in the loose ball in for 1-1.
WGC brought on Aaron Cato and Reggie Ross in going for the win, but it was Broxbourne who got themselves in front with their second, scrambled goal before being reduced to 10 men just two minutes later, Murad flattening Cato with a very high tackle that Mr Ball felt warranted a straight red card.
Ross produced a fine deep cross that cleared the entire home defence for Norris to meet on the volley and crash against the home woodwork with six minutes remaining, but despite a late rally, WGC couldn't find an equaliser on what was a disappointing night.
WGC: Croft, Lovell (James 82), Kenna, Dekanski, Brettell, Arnott (M) (Cato 61), Boodhoo, Smith, Arnott (C), Caswell (Ross 73), Norris.
