Battle of Borny–Colombey

Like most of the early battles of the war, Borny was one that neither side had planned or wanted. For the French, the battle had dire consequences as they neglected to use their numerical superiority to force a passage and it delayed the Army's retreat out of Metz for twelve precious hours. This gave the Prussians the time to bring up their Second army under Prince Frederick Charles and assured that after the battles fought in the following days (Mars-la-Tour and Gravelotte) France's premier army would be trapped at Metz.
