Robshaw was retained as captain for the 2015 Six Nations Championship, and played every minute of England's campaign. He was widely praised for his captaincy as England won the opening game 21-16 away in Wales, with the captain contributing a mammoth 26 tackles. However, the game started five minutes late because Robshaw engaged in a standoff in the Millennium Stadium tunnel, refusing to take his side out only to be left waiting in the cold by the Welsh. However, England fell agonisingly short of the title on the final day of the championship, beating France 55-35 whilst needing to win by 27 points. This meant England would finish second for the fourth time in a row under the leadership of Robshaw and coach Stuart Lancaster.
