How many times was Henry the 2 whipped?

Henry II of England was reportedly whipped three times as part of a penance for his role in the murder of Archbishop Thomas Becket in 1170. This act of self-punishment was meant to demonstrate his remorse for Becket's death, which had caused a significant rift between the monarchy and the Church. The most notable instance of this penance occurred at the shrine of Becket in Canterbury.
