, a 19th-century illustrator. On 10 February 1306 Robert the Bruce participated in the killing of John Comyn before the high altar of the Greyfriars Church in
Dumfries. Legend, possibly apocryphal, says Robert the Bruce called Comyn to a meeting. After Sir Richard Edgar encouraged Robert to slay the Red Comyn, saying: "Maun dae it," Robert stabbed him and rushed out to tell
Roger de Kirkpatrick. Kirkpatrick went in to finish the job uttering: "You doubt! I mak siccar!" ("I make sure!") while
Sir Robert Fleming decapitated Comyn, presenting the head to Robert, stating: "Let the deed shaw" ("Let the deed show"). Apart from these bare facts, nothing certain can be gathered from contemporary accounts. While later Scottish sources all try to justify the crime by amplifying earlier accusations of malevolence and treachery against Comyn, the English sources portray Robert as a villain who lured Comyn inside a church – taken as a guarantee of safety – to commit a premeditated and
sacrilegious murder before the
Real Presence. Some sources state that Bruce and Comyn had previously signed a pact, whereby one would take the crown in return for the lands of the other. As they stood before the
high altar, Bruce accused Comyn of having betrayed by planning to hand him over to the English and struck Comyn with a dagger. It is unknown if this account is true. Bruce's companions struck him with their swords. Sir
Robert Comyn, rushing to aid his nephew, was killed by a blow to the head by Bruce's brother-in-law,
Christopher Seton. Thirteen days after the event, a garbled version of the facts reached the court of
Edward I at
Winchester, where the murder was reported as "the work of some people who are doing their utmost to trouble the peace and quiet of the realm of Scotland." Once the picture became clear, Edward reacted in fury, authorising
Aymer de Valence, Comyn's brother-in-law, to take extraordinary action against Bruce and his adherents by granting
no quarter to them. King Edward also emphasised his blood relationship with the Comyns by ordering his cousin, Joan, to send John's young son and namesake to England, where he was placed in the care of Sir John Weston, guardian of the royal children.
John IV Comyn grew to manhood in England, not returning to Scotland until 1314, when he was killed at the
Battle of Bannockburn. The assassination of his father plunged Scotland into a brief but bloody civil war, largely concluded by 1308, but with political reverberations that were to last for decades. ==References==
