CP correction - death of William de Warenne, 3rd earl, in January 1148
9/5/19Peter Stewart
In CP vol xii part 1, p. 497 William is stated to have died on 19
January 1147/8 "when the rearguard of the French King's army was cut to
pieces in the defiles of Laodicea". This was the battle at Cadmos
mountain, when Louis VII had to fight his way to safety after being
separated from his guard including William, Gaucher II of Châtillon &
Montjay and Evrard III of Breteuil, who were killed.

However, the battle took place ca 7 January, certainly before 19th which
was the date given without citing any authority by George Watson in *The
Genealogist* (1895), referenced in CP as "G. W. Watson in Genealogist,
N.S., vol. xi, p. 132, and authorities there cited". Odo of Deuil, who
was present, said that the battle took place on the day after the king's
army set off from Laodicea, and they had stayed there only a few days
after arriving on 3 or 4 January.

Jonathan Phillips in his chronology in *The Crusades, 1095–1204*, second
edition (2014), p xvii, placed the battle definitely on 7 January, but
other historians have estimated 6 or 8 of the same month.

I'm guessing -- let me know if I'm wrong -- that this correction should
also apply to the death date of Gaucher II de Châtillon, husband of
Alde de Roucy, at least as given on Genealogics.

Genealogics gives his death date as "19 Jun 1148", but the attached bio
says he was "killed in the winter of 1147/48 in a battle at Laodicea in
Anatolia", making it very likely that "Jun" is a typo for "Jan." And
that, per Peter Stewart above, "19 Jan" should be further corrected to
"circa 7 Jan" of the same year.
