The hosts twice stole possession from the Blues to score, with Tom O’Connor’s first half strike added to by Daniel Jebbison.
Reeco Hackett-Fairchild came off the bench to reduce the deficit with a fine free-kick, but there was to be no equaliser.
Danny Cowley stuck with the same side that were unfortunate to pick up just a point at Charlton on Saturday.
There was one switch among the substitutes, however, as Arsenal loanee Miguel Azeez made way for Michael Jacobs.
It was the home side that made the brighter start and when a free-kick was only partially cleared, Michael Bostwick’s shot had to be turned around the post by Gavin Bazunu.
Jonny Smith then angled an attempt wide of the post before Jebbison saw efforts blocked by Kieron Freeman and Sean Raggett in quick succession.
But then it was Pompey’s turn to take control and when John Marquis rose to meet Mahlon Romeo’s cross, his header was saved by Ben Garratt.
Romeo then had a chance of his own after cutting inside from the right and hitting a fierce left-footed strike narrowly off target.
And a hooked Joe Morrell clearance up the pitch soon led to a race between Garratt and Ronan Curtis.
It was the keeper that just about got their first and although he made a mess of dealing with the danger, the ball would not fall kindly for the Pompey forward to capitalise.
Both sides were looking capable of breaking the deadlock as the first half progressed and the rain kept falling.
But it was the Brewers that did score on 32 minutes after stealing possession, with Lucas Akins squaring for O’Connor to fire home from the edge of the box.
And although it was Pompey who were on top as the interval approached, they could not find that crucial final ball to trouble their hosts.
Burton Albion 1
The contest did not spark immediately into life after the restart and the Blues were still struggling in the final third.
There was a chance when Lee Brown’s cross was flicked on by Curtis, but Romeo could not keep his hooked shot down.
Burton were not just sitting on their lead, though, and it took some last-gasp defending from first Freeman and then Raggett to deny them.
And it then required a superb diving save from Bazunu to keep out a swerving long-range strike from Charlie Lakin.
But the hosts did double their lead on the hour mark, as Pompey got caught in possession again and Jebbison took advantage by curling home.
Cowley immediately responded with a triple change, as Marquis, Freeman and Ryan Tunnicliffe made way for Ellis Harrison, Louis Thompson and Hackett-Fairchild.
It was the latter who got the Blues back into the contest, with HACKETT-FAIRCHILD’s fine free-kick flying into the net following a foul on Morrell.
That gave the large travelling army of fans reason to cheer – although they had barely stopped since the first whistle.
Burton kept looking to attack themselves and Lakin missed a great chance when the ball found him unmarked at the back post, only for the midfielder to swipe at thin air.
Bazunu then came to the rescue, using his legs to make a save when a ricochet sent Akins through on goal.
Pompey immediately launched a quick break up the pitch and Harrison took a tumble to the turf, but referee Tom Nield waved away his appeals.
And when the ball fell for Thompson on the edge of the box soon after, the substitute’s shot was deflected inches off target.
The game threatened to boil over in the closing stages, with a series of yellow cards being brandished by the rather fussy Nield.
A display of six additional minutes then provided some hope, but efforts from Thompson and Harness were blocked and time ran out for the Blues.

DRAWN DRAWN LOST LOST LOST LOST DRAWN WON WON LOST
Pompey twice let a lead slip and were forced to settle for a point against Charlton, despite a largely impressive performance at The Valley.
Ronan Curtis had given them an early advantage with an excellent strike and it was a dominant display before the break.
The hosts were better in the second period, however, and substitute Sean Clare levelled before Harness hit back for the Blues.
But with time running out, another replacement struck for the Addicks, with Josh Davison ensuring the spoils would be shared.
Danny Cowley stuck with the same side that dramatically drew with Plymouth on home soil earlier in the week.
It meant that Sean Raggett made his 100th appearance for the club, flanked by Shaun Williams and Kieron Freeman in a back three.
Former Pompey players Craig MacGillivray, Jason Pearce and Jayden Stockley all started for the hosts, while Stephen Henderson was on the bench.
The visitors came charging out of the blocks and it came as no surprise to see them break the deadlock on six minutes.
It was a fine goal from CURTIS, who collected a pass from Mahlon Romeo and sent a shot dipping over MacGillivray and underneath the crossbar.
Charlton almost hit back immediately when Elliot Lee raced onto Jonathan Leko’s pass and fired in a low effort that hit the inside of Gavin Bazunu’s leg and flew narrowly past the post.
The Blues were the team in control, though, and the home support were growing increasingly frustrated at the way their side were being cut through.
Manager Nigel Adkins was the focus of their ire, while his Southampton connections ensured the travelling fans also offered plenty of stick.
Only some fine defending from Pearce and Adam Matthews prevented Harness and Marquis respectively from testing MacGillivray.
The lead should have been doubled on 19 minutes when Harness found Marquis unmarked in the box.
He took a poor first touch, however, and despite recovering to get a shot away, could only screw the ball wide.
Pompey were showcasing some neat passing football and looking capable of adding to their slender lead.
But the Addicks finally enjoyed some joy going forward towards the end of the first half and Bazunu had to adjust his feet to deal with a swerving Leko strike.
Alex Gilbey then surged forward and swapped passes with Leko before hitting a low effort that Bazunu kept out with his leg.
The visitors had the final say before the break, though, and Marquis flicked a Ryan Tunnicliffe delivery narrowly wide.
Charlton Athletic 0
While Pompey had started the first half in impressive fashion, it was their opponents who were brighter straight after the restart.
Raggett conceded a free-kick to the right of the box and the free-kick was cut back by Lee for Clare – who had been on the pitch for a matter of seconds – to slot home the equaliser.
The Blues looked to build again, although Curtis could not repeat his earlier magic after finding space to run into and dragged a shot wide.
And the Addicks were still looking threatening at the other end, with Lee’s strike forcing Bazunu into action.
Lee Brown had tried to halt that attack with a cynical foul on Clare and referee Antony Coggins went back to book the skipper.
It was then Pompey’s turn to challenge, although Curtis’ cross was just behind Romeo, whose header lacked the power to properly trouble MacGillivray.
The action was continuing to switch from one side of the pitch to the other and a Charlton corner almost led to the visitors retaking the lead.
Curtis broke quickly up the pitch and slipped in Harness and he tried to find Marquis in the middle, but Clare slid in to make a crucial interception.
They did go back into the lead on 72 minutes, however, as Tunnicliffe’s pass was neatly flicked on by Marquis for HARNESS to confidently slide into the net.
Pompey set about trying to wrap things up and MacGillivray was called into action twice in quick succession to deal with shots from Harness and Marquis.
A change soon followed from Cowley, with Reeco Hackett-Fairchild coming on against his former club in place of Harness.
And another switch came along moments later, as George Hirst replaced the tireless Marquis up front.
But Charlton hit back in the closing stages, with two of their substitutes combining to find another equaliser.
Corey Blackett-Taylor escaped down the right and squared the ball for the onrushing Davison to slam home from close range and deny the Blues a win.

Pompey have completed the signing of 20-year-old midfielder Jay Mingi, subject to EFL approval.
The West Ham youth product has put pen to paper on a one-year deal, with the club option of a further 12 months.
He had been on trial at Fratton Park over the summer after leaving Charlton at the end of last season.
Mingi made two senior appearances for Charlton, featuring in Papa John’s Trophy games against Brighton U21s and Leyton Orient.
It appeared as though the Blues were slipping to a fourth successive League One defeat after Ryan Hardie raced clear to score twice in the second half at Fratton Park.
That came after Lee Brown had doubled his tally for the season by converting a low free-kick for the hosts in the early stages.
Argyle were seemingly heading for the third tier summit, but Pompey kept pushing and were rewarded for their efforts with Raggett’s late contribution.
Danny Cowley made three changes from the side beaten by Cambridge – also on home soil – at the weekend.
Kieron Freeman, Joe Morrell and John Marquis all returned to the starting line-up, as Paul Downing, Miguel Azeez and Ellis Harrison dropped to the bench.
It meant a switch to a 3-4-1-2 system, with Freeman and Shaun Williams either side of Raggett at the back.
Ronan Curtis moved into a more advanced position alongside Marquis, while Marcus Harness floated in behind.
And the change had an instant impact, as the home side broke the deadlock with less than six minutes on the clock.
Conor Grant was booked for bringing down Mahlon Romeo just outside the box, although Pompey players felt the punishment should have been harsher.
Curtis shaped to shoot, but instead it was BROWN who took the free-kick, slotting it under the leaping wall and into the net.
There was a moving tribute to young Blues fan Sophie Fairall, who lost her brave battle with cancer earlier in the week.
Both sets of fans broke out into applause in the 10th minute, with all the players all stopping to join in.
There was then almost another goal when a low Romeo delivery was only cleared as far as Ryan Tunnicliffe.
He tried to sneak the ball inside the near post, but Mike Cooper got down to his left to push it behind.
The contest turned niggly as the first half developed, with referee Carl Brook dishing out a total of six bookings – three for either side – before the break.
Plymouth threatened themselves as the action progressed and Gavin Bazunu dealt with Luke Jephcott’s long-range effort.
Hardie then met Grant’s pass into the box with a neat flick that flashed a matter of inches past the post.
At the other end, Brown tried to repeat his earlier trick in stoppage-time, but this time slammed a free-kick straight into the wall.
Plymouth Aryle 0
The hosts were looking for a strong start to the second half, only to concede within three minutes of the restart.
It came from their own corner, with the ball hacked up the pitch and Freeman only able to head it into the path of Hardie.
The striker raced up the pitch with only the keeper to beat and neatly lifted home his shot to draw Argyle level.
There was a positive reaction from the Fratton faithful, who continued to get behind their side after that setback.
But the goal certainly seemed to knock the players off their stride, with a few sloppy passes seeing moves break down.
Plymouth were next to seriously threaten, with Bazunu off his line to deny Jephcott and the Blues then surviving a scramble in their box.
There was soon a chance at the other end, though, as Romeo’s effort was blocked by Ryan Broom, while Curtis could not get enough power on his header when the ball ran loose.
Romeo was looking particularly lively for the Blues and met Harness’ cross with a fierce volley that rattled the post, although he had strayed narrowly offside.
And they went close again moments later following some neat passing play involving Morrell and Harness.
The latter’s low centre was turned across the face of goal by Curtis, but a stretching Marquis could not guide the ball on target.
Both sides were looking capable of scoring a winner, with the action quickly switching from one end of the pitch to the other.
It was Plymouth who went ahead on 80 minutes, though, after Williams misjudged a Panutche Camara pass and Hardie broke clear to score his second of the night.
A gamble was needed and Freeman and Brown were sacrificed for forwards Reeco Hackett-Fairchild and Harrison.
But Argyle were using up whatever time they could to see out the closing stages – and it appeared they had done their job.
Then, in the final seconds of stoppage-time, Curtis swung in a fine cross that was nodded down by Harrison and RAGGETT turned the ball home from close range.
There was a mixture of relief and delight as Fratton Park erupted, with the final whistle sounding moments later.

I have just finished this classic show, created by Brian Clemens and first shown on British TV between 1977 – 1983.
What a breath of fresh air compared to modern TV, a total lack of political correctness, unashamed machismo and sexism, and a great insight into London when it still felt like a major English city.
Strange to think prior to this Gordon Jackson was most famous for being a butler.
Well it was earlier than expected but our friendly new owners Standard Aero has announced they are going to make redundancies, at least 20 will go across the company in theory in view of the downturn in the aviation industry due to Covid.
When they gave their presentation upon taking us over the sense was “we are your friends, shoot to kill!”
