The Magpies came from 2-0 down to earn a valuable point at Anfield.
Goals from Daniel Sturridge and Adam Lallana inside the first half-hour at Anfield appeared to have left the Magpies' mini-revival under Benitez in tatters.
However, Papiss Cisse and Jack Colback would score in the second-half to ensure that Benitez's men extended their unbeaten run to three games, and took themselves to within one point of safety in the Premier League.
And Townsend appeared to confirm that it was the manager's message at the break that changed the game for the away side.
"He [Benitez] basically said: 'You've got nothing to lose now - keep going and leave it all on the pitch'," he told the Chronicle.
Similarly, Cisse credited the Spaniard's manner at the interval as the turning point that inspired the comeback, the Chronicle reports.
"He was not angry, he talks to us normally," he explained to the Chronicle.
"The players all listen to him. If you have a gaffer like this the only thing you want to do is go outside and fight for him. It helped us come back."
With Jurgen Klopp's men scoring 14 goals in their last four games in all competitions, many Newcastle supporters may have feared that the confidence that the club had picked up from the win over Swansea and draw against Manchester City had evaporated.
However, they showed the same fighting spirit that was on show against City in midweek to earn a point and prove to their relegation rivals that they are still in with a good chance of being the ones that ultimately get their heads above water.
