David Wagner's side were effectively undone by two contentious first-half decisions from Wiltshire referee Roger East as Newcastle United extended their lead at the top of the table by five points and 11 points ahead of third-placed Town.
After a bright start from the home side, Matt Ritchie scored from the penalty spot in the 10th minute after Nahki Wells was adjudged to have fouled the winger in the box.
The Magpies doubled their advantage just after the half hour mark, Daryl Murphy prodding home as Town's players were left incensed at a perceived foul on goalkeeper Danny Ward in the build up.
Town rallied in the second-half with Aaron Mooy giving the home side a glimmer of hope from the spot in the 72nd minute only for Dwight Gayle to extinguish it late on as the home side chased an equaliser.

Moan of the Match
As the rain came down, the pitch cut up - not conducive to Huddersfield Town’s preferred passing style of play.
Was it a penalty? Was it a foul on Danny Ward for the second? Two key decisions that changed the course of the game.
Man of the Match
Rajiv van La Parra - positive and hard-working throughout, his head never dropped when it arguably did for some others around him.
Tweet of the Match
Roger East (Wiltshire) - two contentious first-half decisions marred what could have been an open and even SkyBet Championship contest.
Electrifying only to be slightly dampened by the two fortuitous goals scored by the visitors and becoming hostile towards the referee.
A disappointing result for Town but with Brighton & Hove Albion losing away to Nottingham Forest earlier in the day, automatic promotion is still not beyond their reach.
