England picked up an impressive 12-6 victory over Six Nations rivals Ireland on Sunday in an absorbing 80 minutes at the Aviva Stadium in Dublin.
Stuart Lancaster's outfit put in another mature effort that leaves them as the last remaining unbeaten side in the 2013 Championship.
No tries were scored in the spectacle but the English displayed an edge that denied Ireland, who had crossed for three tries against Wales, any real opportunity to get over the whitewash.
Owen Farrell kicked all of England's points, but it was their intelligence with and without the ball that ultimately won the game as Ireland struggled to get into the match, due in part to losing Simon Zebo and Jonathan Sexton to early injuries.
Farrell gave England an early lead with a second-minute penalty but Dublin tempers flared in the fourteenth minute when Ireland prop Cian Healy's apparent use of the boot on England tighthead Dan Cole at a ruck sparked a mass brawl.
Both packs managed to slow their opponents' ruck ball and neither side had a genuine chance of a try in the first-half of a match featuring several candidates for the Lions tour.
In such a tight contest, discipline was especially important, and Farrell punished Ireland for coming round the wrong side of a ruck with a superb penalty from nearly 50 metres out.
Ireland lost fly-half Sexton with a hamstring pull just after the half-hour mark, although the wet conditions put a premium on the kicking game for which Ronan O'Gara is renowned.
But when O'Gara, Ireland's most capped player, held on too long in the tackle, following good work by England defensive linchpin Brad Barritt, it gave Farrell a long-range penalty chance on the stroke of half-time. However, his kick just went wide.
Early in the second period Ireland won a scrum penalty and O'Gara cut the deficit in half.
Coach Lancaster stiffened his side's physical presence by bringing on centre Manu Tuilagi for Billy Twelvetrees and Courtney Lawes for lock Joe Launchbury in the 48th minute.
England, though, were a man down in the 57th minute when blindside James Haskell, was yellow carded by French referee Jérôme Garces for kicking the ball out of a ruck.
O'Gara landed the ensuing penalty to tie the match at 6-6 heading into the final quarter. Yet despite being reduced to fourteen, England then outscored Ireland 6-3 in the ten minutes.
Farrell's clever kick ahead set up an England line-out close to Ireland's line and then Tuilagi was just unable to get a touch for a try after a neat chip ahead by scrum-half Ben Youngs.
However, Garces had already awarded England a penalty from inside the 22 and Farrell made no mistake to nudge his side into a 9-6 lead. And that became 12-6 when the composed Farrell landed his fourth penalty after Ireland infringed by not releasing.
Ireland then saw O'Gara miss an eminently kickable penalty from just outside the 22 and England's defence held firm for a result that puts them two points clear at the summit.
Man of the match: While the official award went to captain Chris Robshaw, who was superb as a leader, we believe that Ben Youngs had a slightly better shift in Dublin. He organised his pack well while his kicking for position was outstanding in difficult conditions. Rarely does Danny Care not make it onto the field but today Youngs was not to be disturbed.
Moment of the match: After Ronan O'Gara had kicked three points following England's James Haskell kicking the ball out from a ruck, the visitors showed real character to record their own points while the flank was in the sin-bin. In such spells wins are earned.
Villain of the match: There were two occasions when Cian Healy lost his cool and it is now expected that the Irish loosehead prop will face a trip to a hearing. The first indiscretion saw him stamp on Dan Cole's ankle before he led with the elbow in a ruck. Not good at all.

A solitary late try from wing George North handed Wales the spoils in a dour game that culminated to the sound of boos and whistles from the Parisian crowd.
Four tries, including a brilliant length of the field interception try from Stuart Hogg, led to a memorable victory for Scotland in front of a vocal home crowd at Murrayfield, compensating for the performance against England at Twickenham last weekend.
It was a sensational victory for the Azzurri who have now managed to beat Les Bleus twice in the last two years following their famous win in 2011.
The hosts enjoyed large portions of possession in both halves and arguably should have come away with more points, despite racking up four tries through Chris Ashton, debutant Billy Twelvetrees, Geoff Parling and Danny Care.
A dire performance from Wales in the opening 40 minutes left them with a mountain to climb in the second-half, at which they threw everything to bounce back from a 30-3 scoreline to 30-22 in an utterly dominant half.
The loss meant that Wales, the current Grand Slam champions and World Cup semi-finalists, fell out of the top-eight seeds for RWC 2015, the draw for which takes place on Monday.
New Zealand responded to a 15-0 defecit with scores from Julian Savea and Kieran Read, before England took charge thanks to three of their own from Brad Barritt, Chris Ashton and Manu Tuilagi in an astonishing second-half performance.
The visitors crossed the whitewash on five occasions with Wyles bagging a brace, while Andrew Suniula, Paul Emerick and Takudzwa Ngwenya also added their name to the scoresheet.
Three penalties from Pat Lambie and a bizarre try from Willem Alberts handed the visitors the win, with Toby Flood and Owen Farrell accumulating five penalties between them.
Ireland led from start to finish in a dominant display, outscoring their visitors seven tries to two.
Unlike their convincing successes over Australia and Argentina this month, victory didn't come easily for the French, who were trailing the Islanders going into the final quarter.
Predictions the All Blacks' attack would incinerate Wales' defence came to fruition in the first half especially. However even though the scoreline may read otherwise, it was a much better effort from the Welsh - the second half especially.
Scotland led 6-3 at half-time but second-period tries from Tukulua Lokotui and Fetu Vainikolo saw the Pacific Islanders earn their first ever Test triumph on the European stage
A superb second half fightback almost saw the home side pulling off a draw but a penalty from their fly-half Luciano Orquera, in the 79th minute, sailed just wide of the posts.
In a lacklustre but testy match, the Maori scored two tries to one plus 22 points from Willie Ripia.
Winger Fetu'u Vainakolo grabbed the opening score for the Islanders with a try after ten minutes, before the USA's Luke Hume looked to have levelled the scores only for this try to be ruled out for a forward pass.
A dominant first-half performance saw the visitors take a 14-3 lead into the interval thanks to Strauss's first try — off a rolling maul that Scotland failed to deal with — and three penalties from Pat Lambie.
With England, Wales, Scotland and Italy losing to southern opposition this weekend — Ireland were playing in a non-cap international — the French confirmed their status as the top European team in the world rankings.
The result is Canada's third consecutive win over the Bears.
Gilroy was the star of the show while Fergus McFadden grabbed two tries and Sean Cronin, Darren Cave and Luke Marshall added the gloss.
