Note 40 — Chapter III
Reading edition
This is the date commonly given. The Annual Register, li. (1809), 239, gives the 22nd, while Perceval refers to the result of the duel in a letter dated the 20th (Colchester, Diary, ii., 209). It is clear, however, that Canning did not receive Castlereagh's challenge till the morning of the 20th (see his letter in Annual Register, loc. cit., 505, also his detailed statement to Camden, ibid., 525), and therefore the duel cannot have taken place till the 21st. Lord Folkestone in a letter dated the 21st refers to the duel as having been fought at "7 o'clock this morning" (Creevey Papers, i., 96).
