Originally published by H.M. Stationery Office in London in 1877, Tactical Studies of the Battles of Columbey-Nouilly and Vionville was compiled and analysed by Major Lonsdale Augustus Hale, later Sir Lonsdale Hale. It provides a precise tactical study of two important engagements during the opening stages of the Franco-Prussian War. Hale examines the Battle of Columbey-Nouilly on 14 August 1870 and the Battle of Vionville on 16 August, tracing the movements and deployment of the opposing forces. Particular attention is given to infantry attacks, artillery employment and the influence of terrain on the course of operations. The study highlights how the Prussian forces, despite being substantially outnumbered, succeeded in checking the French advance and compelling the French Army towards the fortress of Metz. Combining close tactical observation with professional military analysis, Hale's work offers a valuable contemporary British assessment of two consequential battles of the 1870 campaign.
