Striker Wayne Rooney added: “It’s good to get that history of what happened. It puts football into perspective.”
Rooney was joined at Auschwitz - where an estimated 1.1 to 1.5 million people died during World War II - by England team-mates Joe Hart, Phil Jagielka, Theo Walcott, Jack Butland, Andy Carroll and Leighton Baines.
After walking through the gas chambers and crematoria of Auschwitz, Rooney described his feelings of near disbelief.
"It’s hard to understand," Rooney said. "I am a parent and it was tough to see what happened there.
"You’ve seen the amount of children who died. You see the children’s clothes and shoes, it’s really sad.
"You have to see it first hand. You don’t realise how those who lived there to work managed without food, without water. It’s a form of torture and then they died. The others got murdered."
England coach Hodgson added: “I have no great knowledge of the war, but obviously know about certain aspects of it.”
"You cannot understand how it can be so systematic, dehuman. It was a job. It is difficult to get your head around.
"There are so many lessons to be learnt and understood from the Holocaust and we believe football can play its part in encouraging society to speak out against intolerance in all its forms - and in advancing the important work of teaching future generations about the horrors of the Holocaust."
People need to vigilant to ensure nothing like this ever happens again. There are far too many examples, albeit on a much smaller scale, of people engaging in the same kind of dehumanizing thinking that led to this atrocity. Even right now in Poland itself (and Ukraine) players being subjected to racist chants and other abuse.
