TOWN stormed into the quarter-finals of the FA Cup for the first time in 17 years.
Ian Greaves' side beat West Ham 4-2 in front of 27,080 at Leeds Road in a match described as undoubtedly Town's greatest triumph in years.
The stunning victory gave Town a sixth round tie at Second Division Birmingham City.
But at half time the fans had begun churning out stories of bad luck.
After dictating practically all the first half and going justifiably in front with a Jimmy Lawson goal on 24 minutes, they were unfortunate to concede a `Pop' Robson equaliser in first half stoppage time.
On the second half resumption, however, the Terriers stormed back with a brand of determination and attacking power the likes of which you would have had to delve a very long way back in the history books to recall.
Inside six minutes a snap 18-yarder by Terry Dolan had restored Town's lead and then on 68 and 70 minutes, West Ham's normally tight and reliable defence was shattered with goals by David Smith and Frank Worthington.
From that point on, it was a question only of the size of the margin by which Town would win.
A 4-2 final score was, if anything, kind to Ron Greenwood's men.
Brave goalkeeping by Bobby Ferguson coupled with a late consolation `gift' goal just softened what could have resulted in utter humiliation for the Hammers in the second half.
For his part, boss Ian Greaves saw little difference in his team's performance that day to many of those which they had played in the League's top flight but had got little or no reward.
"If there was a difference today, then it was that this time after we had created the openings the ball finished in the right place," said Greaves.
Town's forwards, with Worthington a shining example, swiftly and skilfully took opponents on, going for goal the short-cut way. It was as if the West Ham defence was struggling to keep tabs on five and six Francis Lees all at one go as Bobby Moore and Co found their defensive system creaking all over the place.
Town scored four goals - it should have been six, with all due respect to West Ham who, in spite of eveything, played football right to the end.
