From _An Impartial History of the War in America_, vol. i. p. 392 (Boston), engraved by J. Norman. Cf. the engraving in Murray's _Impartial Hist. of the Present War_, ii. 193. Neither of these copper-plates are probably of any value as likenesses. They show the kind of effigy doing service at the time.] The great resource for original material on the siege of Quebec, beside the letters given by Sparks and Lossing, are in the gatherings of _4 Force's Archives_, vols. iv., v., and vi.; Almon's _Remembrancer_, vol. ii.; _N. Y. Col. Docs._, viii. 663, etc.; and in a large number of diaries and other contemporary records, which may readily be classed as American or British, with a few emanating from the French Canadians.[647] On Jan. 19, 1776, a report was made in Congress that the army in Canada be reinforced (_Secret Journals_, i. 241). [Illustration From an engraving of full length in _An Impartial Hist. of the War in America_, Lond. 1780, p. 249. A mezzotint similar to this was published in London, 1776, as "Col. Arnold, who commanded the provincial troops sent against Quebec" (J. C. Smith, _Brit. Mez. Portraits_, iv. 1714-1717). The portrait in profile, by W. Tate,—a handsome face,—was engraved in line by H. B. Hall in 1865, and etched by him in 1879 for Isaac N. Arnold's _Life of B. Arnold_. Cf. Jones's _Campaign for the Conquest of Canada_, p. 168. Other portraits of Arnold are given later in the present volume.] [Illustration: MONTRESOR'S MAP. Sketched from the original (1760) among the Peter Force maps in the Library of Congress. There is a copy in the library of the N. E. Hist. and Geneal. Society.] In April Arnold returned to Montreal, and Wooster took command before Quebec,[648] to be superseded by General Thomas, who reached the camp May 1st. Upon Carleton's being reinforced, Thomas began to retreat.[649] Burgoyne arrived with additional troops in June (Fonblanque's _Burgoyne_, 211). The affair at the Cedars took place May 19, 1776.[650] The movement against Three Rivers had been begun by orders of Thompson, who was in command upon the death of Thomas (June 2d), and remained so for a few days till Sullivan arrived. [Illustration: From _An Impartial History of the War in America_, Lond., 1780, p. 400, where the cut represents his full length. Cf. prints published in London in 1776 (_Brit. Mez. Portrait_, by J. C. Smith); Hollister's _Connecticut_, i. 390; Jones's _Campaign for the Conquest of Canada_, 28; _Geschichte der Kriege in und ausser Europa_ (Nürnberg, 1778).] Smith, in the _St. Clair Papers_, i. 17, collates the authorities on this movement,[651] calling in question the statements given by Bancroft. Sullivan's Irish precipitancy and over-confidence did not mend matters as the retreat went on, and raised delusive hopes which were more welcome than Arnold's gloomy views.[652] [Illustration: SIEGE OF QUEBEC, 1775-76.
