No English side had won an RBS 6 Nations match in Dublin for a decade, since Martin Johnson's team completed a Grand Slam at the old Lansdowne Road. Owen Farrell kicked four penalties as England delivered a performance of ferocious intensity to pass their biggest test of character since Stuart Lancaster took charge.
"We came here to put a marker down and we will build on that," said Robshaw, who was named man of the match.
"We knew we hadn't won here in 10 years and we knew why. Today we got it spot on.
"We are always fired up and the message today was 'no backward step', whether it is little off-the-ball stuff or going after them from minute one and we did that today.
"It was all about defence at the end of the day and someone like Owen kicking the goals. That performance was definitely right up there."
