Walter Tirel III[a] (1065 – some time after 1100), nicknamed the "Red Knight of Normandie", was an Anglo-Norman nobleman.
The grandson of Walter and Adeliza, Hugh Tyrrel, took part in the Norman Conquest of Ireland and became the first baron of Castleknock.
On the subsequent hunt, the party spread out as they chased their prey, and William, in the company of Tirel, became separated from the others.
Even chroniclers of the time point out that Walter was renowned as a keen bowman, and unlikely to loose such an impetuous shot.
Henry, who once threw a man off a tower to his death,[1] was not normally troubled by moral scruples: on the other hand it has been argued that fratricide was then regarded as a particularly horrible crime,[2] and even the suspicion of it would have done great harm to the new King's reputation.
