Britain's Captain Tom Moore, the World War II veteran who raised millions of pounds for health service workers battling the coronavirus, received online abuse in the weeks before he died this month aged 100, his daughter has said.
Hannah Ingram-Moore told BBC television the online messages were kept a secret, saying the abuse from "a vile minority" would have broken his heart.
Capt Moore struck a chord with locked-down Britain by walking around his garden with the help of a frame to raise £38.9m (€44.7m) for the National Health Service.
While he received tens of thousands of supportive messagesthere were some that mocked and abused him.
"It was as pretty horrific as it could be," saidIngram-Moore.
"I couldn't tell him because how do you rationalise to a 100-year-old man that something so incredibly good can attract such horror," she said.
"It really did hurt and it really is hard to deal with but we have dealt with it and they will not win, they will never make this amazing thing negative."
With a quick wit, Capt Moore brought a simple message of hope and self-sacrifice. He died on 2 February after testing positive for Covid-19 on 22 January, and he was also fighting pneumonia.
Calls for social media companies to block users who send abusive messages have grown in recent weeks after several soccer players in England were targeted with racist abuse.
