Recent history indicates that, in most, if not all, future military conflicts, the United States will participate as part of a coalition. Examination of successful coalitions from the past may reveal precepts which can be applied in order to successfully approach participation in future coalitions. The Battle of Leipzig in 1813 is a superb example of successful coalition operations from early 19th Century. Its detailed study and analysis has led the author to the conclusion that, different principles apply to successful prosecution of coalition operations at each level of war. Understanding and orchestrating the precepts that apply at each level will give the United States the best chance for successful prosecution of its future strategic objectives during war.
