Description:
This large original lithograph print, schematics of various forts in and around the French city of Lyons - during the time of the Crimean War and just prior to the American Civil War - was engraved by John T Bowen & co. of Philadelphia and was published in the 1856 edition of Captain Richard Delafields Report on the Art of War in Europe in 1854, 1855, and 1856.

In early 1855, Captain Richard Delafield was appointed by the Secretary of War, Jefferson Davis, a head of the board of officers, later called The Delafield Commission, and sent to Europe to study the European military. The board included Captain George B. McClellan and Major Alfred Mordecai. They inspected the state of the military in Great Britain, Germany, the Austrian Empire, France, Belgium, and Russia, and served as military observers during the Crimean War. After his return in April 1856, Delafield submitted a report which was later published as a book by Congress, Report on the Art of War in Europe in 1854, 1855, and 1856. The book was suppressed during the American Civil War due to fears that it would be instructive to Confederate engineers as it contained multiple drawings and descriptions of military fortifications.

Background:
The ceintures de Lyon (Belts of Lyon) were a series of fortifications built between 1830 and 1890 around the city of Lyon, France to protect the city from foreign invasion.
The belts comprised two defensive barriers that included forts, lunettes, ramparts, batteries, and other defensive structures. Many of these structures proved to be ineffective in war due to advancement in weapon technology and the evolution of attack strategies at the time. Some of the fortifications of the ceintures de Lyon have been destroyed, though many remain today.
In 1830 the maréchal de camp, Hubert Rohault de Fleury, commenced a project designed by military engineer Baron Haxo. With a budget of 10,000,000 francs (approximately €67,000,000 as of 2015) allocated for Lyon between 1831 and 1839, this first project included the restoration of the fortifications between Croix Rousse and Fourvière; the construction of two forts on the plateau of Caluire (Fort de Montessuy and Fort de Caluire, connected by the Enceinte de Caluire), facing the Dombes; closing access to the Presquîle by the construction of a south-facing building; building two forts – Fort de la Duchère and Fort de Grange Blanche – to protect access routes towards Paris and Auvergne.
The fortification of the city is divided into three sectors: The north was protected by the wall of Croix-Rousse and the structures between the Rhône and the Saône. The command was situated at fort de Montessuy. The west was covered by the hillfort of Fourvière and the associated forts of Vaise at Sainte-Foy. The command was situated at fort Saint-Irénée. The east was defended by the Redoute du Haut-Rhône and Fort de la Vitriolerie on the left bank of the Rhône. The command was situated at Fort Lamothe.
The work required almost 20,000 workers, which were locally sourced in an attempt to avoid insurrection such as the ongoing unrest of the Lyon silk workers (Canuts) over increased capitalism. Work began in 1831 to build seven structures, each structure requiring between 400 and 500 workers. The scope of this project included the construction of Fort de Montessuy and Fort de Caluire to the north; Fort des Brotteaux, Fort Montluc and Fort du Colombier to the east; the Redoute de la Part-Dieu to the west; and Fort Saint-Irénée, to protect the entire area.
In January 1831, an uprising began at a work site in Charpennes, however it was quickly stopped by the army. Other insurrections took place the same year, a series of Canut revolts, which succeeded in rallying soldiers on the side of the Canuts, resulting in the death of captain Viquesnel, aide-de-camp of Fleury, and the temporary withdrawal of the 20,000 soldiers who eventually retook the city in December 1831.
In 1832, three other structures were built to reinforce the defenses to the east: The Redoute de la Tête dor, Fort La Motte, and the Redoute des Hirondelles. A treaty was signed between the city of Lyon and the War Department, which stipulated that the city had to cede the land necessary for the construction of military buildings to the War Department, while the forts themselves would still belong to the city if the military decided to abandon them. It is thanks to this treaty that the forts of Croix Rousse, Fourvière, Loyasse, Vaise, and Saint-Jean would later be returned to the city.
Construction resumed in 1840. First the Fort de la Vitriolerie in 1840, then Fort de Sainte-Foy-lès-Lyon and the Lunette des Charpennes in 1842, Fort de la Duchère in 1844, the Redoute du Petit Sainte-Foy-lès-Lyon in 1852, and finally the Redoute du haut-Rhône in 1854.
A law was voted in on 10 July 1851, which defined the methods of destruction of these buildings or construction on their land. By 1854, 19 structures including 10 forts had been built around Lyon, creating a nearly 14-kilometre (8.7 mi) fortified perimeter.

Delafield, Richard Major General 1798 - 1873 - Delafield was a United States Army officer for 52 years. He served as superintendent of the United States Military Academy for 12 years. At the start of the American Civil War, then Colonel Delafield helped equip and send volunteers from New York to the Union Army. He also was in command of defences around New York harbor from 1861 to April 1864.

On March 8, 1866, President Andrew Johnson nominated Delafield for appointment to the grade of brevet major general in the Regular Army, to rank from March 13, 1865, and the United States Senate confirmed the appointment on May 4, 1866, reconfirmed due to a technicality on July 14, 1866. He retired from the US Army on August 8, 1866. He later served on two commissions relating to improvements to Boston Harbor and to lighthouses. He also served as a regent of the Smithsonian Institution.

They inspected the state of the military in Great Britain, Germany, the Austrian Empire, France, Belgium, and Russia, and served as military observers during the Crimean War. After his return in April 1856, Delafield submitted a report which was later published as a book by Congress, Report on the Art of War in Europe in 1854, 1855, and 1856. The book was suppressed during the American Civil War due to fears that it would be instructive to Confederate engineers as it contained multiple drawings and descriptions of military fortifications.
Delafield served as superintendent of the Military Academy again in 1856-1861. In January 1861, he was succeeded by Captain Pierre G. T. Beauregard, who was dismissed shortly after Beauregards home state of Louisiana seceded from the Union, and Delafield returned as superintendent serving until March 1, 1861. In the beginning of the Civil War he advised the governor of New York Edwin D. Morgan during the volunteer force creation. Then, in 1861–1864, he was put in charge of New York Harbor defences, including Governors Island and Fort at Sandy Hook.
