England saw the Grand Slam and the RBS 6 Nations title ripped away from them at the Millennium Stadium, going down 30-3 in a comprehensive victory that still lingers with a number of Lancaster's players.
Since then however England have played eight Tests - winning six - and after their impressive 13-10 win over Ireland, they remain in contention for the 2014 Championship.
As do Wales after their emphatic win over France and neither side can afford to lose at Twickenham on Saturday week if they are to remain on course for the title on the final day.
Thoughts of lifting the trophy have been put on the backburner however with the visit of Wales proving the acid test for England's flourishing side.
"Looking back on [last year's defeat], the big lesson we learnt was keeping composure when the score started to turn against us and we've done that in subsequent games," said Lancaster.
"I deliberately remember saying at that time we made a bad job worse and in games against New Zealand, Australia and France since then we've shown we're a lot more composed and a lot more experienced at dealing with those sort of situations.
"The trick obviously is not to put yourself in that position in the first place.
"Last year's loss was hard to take, there's no doubt about it, but no team goes unbeaten in international rugby.
"It's how you respond to the loss that's important and we went to Argentina and continued to develop our game."
