This is an original Civil War infantry tactics manual that is identified to the soldier who carried it. The book itself is the 1854 edition of the third volume of Infantry Tactics manual of Silas Casey. This one was printed by Harper & Brothers of New York in 1854. On the inside cover, it has the soldier's name that carried it. In ancient brown ink, it reads " Silas W. Field / Dupont, Ill. / April 20th 1861". In the records, it shows that Silas W. Field enlisted on April 30th 1861 as a 2nd Lieutenant in the 11th Illinois Infantry. In July of 1861, he was promoted to 1st Lieutenant and then to Captain on February 2nd 1862. During the Battle of Shiloh on April 6th 1862, Field was fighting along the Corinth Road. One report says that Field has his leg "Almost severed" by a Confederate solid shot cannonball. He never recovered but made it home and died on May 9th 1862 surrounded by his family. It still has what appears to be all of the pull-out diagrams and pages intact. You can tell that this book was carried and used. The manual is accompanied by 2 original CDV images of Field in his civilian clothes. It is a great book and 2 images from a soldier that gave all for the Union.
