*ENGLISH ORDNANCE.* For detailed information John Mueller, _Treatise of Artillery_, London, 1756, has been the basic source for eighteenth century material. William Bourne, _The Arte of Shooting in Great Ordnance_, London, 1587, discusses sixteenth century artillery; and the anonymous _New Method of Fortification_, London, 1748, contains much seventeenth century information. For colonial artillery data there is John Smith, _The Generall Historie of Virginia, New-Englande, and the Summer Isles_, Richmond, 1819; [Edward Kimber] _Late Expedition to the Gates of St. Augustine_, Boston, 1935; and C. L. Mowat, _East Florida as a British Province_, 1763-1784, Los Angeles, 1939. Charles J. Foulkes, _The Gun-Founders of England_, Cambridge, 1937, discusses the construction of early cannon in England. *FRENCH ORDNANCE.* M. Surirey de Saint-Remy, _Memoires d'Artillerie_, 3rd edition Paris, 1745, is the standard source for French artillery material in the seventeenth and early eighteenth centuries. Col. Fave, _Etudes sur le Passe et l'Avenir de L'Artillerie_, Paris, 1863, is a good general history. Louis Figurier, _Armes de Guerre_, Paris, 1870, is also useful. *UNITED STATES ORDNANCE.* Of first importance is Louis de Tousard, _American Artillerist's Companion_, 2 vols., Philadelphia, 1809-13. For performance and use of artillery during the 1860's the following sources are useful: John Gibbon, _The Artillerist's Manual_, New York, 1863; Q. A. Gillmore, _Engineer and Artillery Operations against the Defences of Charleston Harbor in 1863_, New York, 1865; his _Official Report ... of the Siege and Reduction of Fort Pulaski, Georgia_, New York, 1862; and the _Official Records of Union and Confederate Armies and Navies_. Ordnance manuals of the period include: _Instruction for Heavy Artillery_, U. S., Charleston, 1861; _Ordnance Instructions for the United States Navy_, Washington, 1866; J. Gorgas, _The Ordnance Manual for the Use of the Officers of the Confederate States Army_, Richmond, 1863. For United States developments after 1860: L. L. Bruff, _A Text-book of Ordnance and Gunnery_, New York, 1903; F. T. Hines and F. W. Ward, _The Service of Coast Artillery_, New York, 1910; the U. S. Field Artillery School's _Construction of Field Artillery Materiel_ and _General Characteristics of Field Artillery Ammunition_, Fort Sill, 1941. *GENERAL.* For the history of artillery, as well as additional biographical and technical details, there is the Field Artillery School's excellent booklet, _History of the Development of Field Artillery Materiel_, Fort Sill, 1941. Henry W. L. Hime, _The Origin of Artillery_, New York, 1915, is most useful, as is that standard work, the _Encyclopedia Britannica_, 1894 edition: Arms and Armour, Artillery, Gunmaking, Gunnery, Gunpowder; 1938 edition: Artillery, Coehoorn, Engines of War, Fireworks, Gribeauval, Gun, Gunnery, Gunpowder, Musket, Ordnance, Rocket, Small arms, and Tartaglia.
