"The Field Engineer: Or Instructions Upon Every Branch Of Field Fortification : Demonstrated By Examples Which Occured In The Seven Years' War Between The Prussians, The Austrians, And The Russians : With Plans And Explanatory Notes" by Johann Gottlieb Tielke. This work is a comprehensive treatise on field fortification and military engineering, detailing the design, construction, and evaluation of defensive works such as parapets, fleches, redoubts, and star forts. It explains techniques for preparing ground plans, trenches, inundations, and water defenses, and provides guidance on defending towns, villages, rivers, and ramparts in various terrains. The text presents numerous chapters with rules for marking out retrenchments, the arrangement of batteries, the use of guileful devices like trous-de-loup, and methods for scaling and copying plans. Embedded are historical references to sieges and campaigns of the Seven Years' War era, illustrating principles through practical examples. The work is a foundational manual for engineers and officers responsible for field fortifications and siegeworks, emphasizing practical geometry, spatial reasoning, and risk-aware defense.
