What did Henry do to say sorry for beckets death?

After the murder of Thomas Becket in 1170, King Henry II expressed deep remorse and guilt for his role in the event, although he did not directly order it. To show his contrition, he undertook a pilgrimage to Becket's shrine in Canterbury in 1174, where he walked barefoot and was publicly penitent. Additionally, Henry imposed a form of penance by allowing the church to punish his knights who were involved in the crime and by making significant donations to the church.
