Scotland evoked memories of Murrayfield 2000 as they destroyed England's Grand Slam dream and blew the RBS 6 Nations Championship wide open.
England suffered Calcutta Cup misery for the first time since Duncan Hodge's heroics inspired a famous Scottish victory six years ago.
And although the world champions did not have to contend with freezing rain and hail this time around, they were blown off course by a Scottish side confident and superior in all key departments.
New coach Frank Hadden has instilled pride and a purpose in his players, and how they responded on an emotionally charged Edinburgh evening.
Chris Paterson was the match-winning star, booting five penalties from five attempts, while fly-half Dan Parks' 57th-minute drop-goal kept England at bay.
Charlie Hodgson kicked all England's points, but Scotland were magnificent in defence and when it came to the scrap for loose ball, driven relentlessly by workaholic flanker Ally Hogg.
England, in contrast, lacked composure at key times, making errors under pressure and losing direction when the heat came on from their opponents.
Scotland's triumph means the Grand Slam cannot be won by any team this season, and only Italy are out of title contention halfway through the tournament.
Somehow, England have now got to pick themselves up for an appointment with France in Paris on March 12, and it could prove the toughest task of head coach Andy Robinson's career.
England, a stone a man heavier up front, were expected to flex their collective muscle from the start, but they put an emphasis instead on moving possession wide, underlined through a second-minute breakout some 80 metres from Scotland's line.
Such adventure set the tone for an invigorating opening spell, with Paterson and Hodgson exchanging penalties either side of both teams being determined to keep ball in hand.
England were the most threatening attacking unit, but their momentum was disrupted when prop Julian White - recalled as replacement for injured Bath tighthead Matt Stevens - was penalised for use of the boot at a ruck.
Australian touch judge Stuart Dickinson brought the incident to referee Alan Lewis' attention and it ruffled England, who found themselves under pressure when full-back Josh Lewsey spilled a steepling Parks kick just inside his own 22.
Scotland looked to attack from the ensuing scrum, yet despite England halting their progress, it came at a cost.
Lock Danny Grewcock's lunge at Kellock incurred Lewis' wrath, and the resulting yellow card depleted English numbers just when they required all hands to the pump.
Hodgson failed to find the target through a 45-metre kick, and with England missing Grewcock's immense physical presence, Scotland's forwards made hay in his absence, securing turnover ball three times in quick succession.
The home side though, failed to score with Grewcock off the pitch, and England ended an enthralling first-half laying siege to the Scottish line with a series of short-range scrums.
But just when it looked as if Scotland might finally crack, England botched a gilt-edged chance.
Impressive scrum-half Harry Ellis moved possession wide from a scrum, only for wing Ben Cohen to drop the ball under no pressure, and the teams trooped off with Perpignan prop Perry Freshwater on for a bloodied Andrew Sheridan.
Scotland would have been far happier than their visitors at a 3-3 interval scoreline, and there was little suggestion of England running riot to match their average 38 points over the past five Calcutta Cup victories.
Sheridan returned for the restart, and England immediately went ahead after Scotland fell offside and Hodgson slotted an easy penalty.
The lead lasted approximately 90 seconds as Paterson bisected the posts from just inside England's half, levelling things up at 6-6 and leaving matters finely balanced.
England could not establish control, and they fell behind for the first time on 47 minutes when Paterson completed his penalty hat-trick after Cohen was punished for not rolling away from a tackle.
Matt Dawson briefly replaced Ellis when he suffered a head wound repelling a Scottish attack, and Parks' drop-goal from 30 metres hoisted Scotland 12-6 ahead.
England boss Robinson had to start using a star-studded replacements' bench, and Lawrence Dallaglio replaced skipper Martin Corry 16 minutes from time in pursuit of a formula to break the wonderfully resilient Scots down.
England continued to enjoy the lion's share of possession, yet opportunities were wasted at a worrying rate, notably when centre Mike Tindall fired out a woeful pass just as Scotland's defence was stretched.
Dallaglio's Wasps colleague Simon Shaw also entered the fray, taking over from Grewcock, but Scotland almost scored when Hogg went for glory and was tackled into touch by Sheridan and Lewis Moody with the line just inches away.
Paterson's fourth penalty sent Murrayfield wild on 72 minutes, and although Hodgson then narrowed the gap to 15-12, a fifth and final Paterson strike completed England's misery.
