After defeat at the Battle of Leipzig, French forces under Napoleon Bonaparte slowly retreated in the first two months of 1814, conducting an aggressive defence and a number of counterattacks against the numerically superior Sixth Coalition.
Napoleon won a series of brilliant victories during the Six Days' Campaign before the Allies forced him to fall back towards Paris.
Napoleon at Bay is a two-player wargame at the operational level that uses a set of rules developed by designer Kevin Zucker.
As would happen with several other OSG games such as Arcola and The Legend of Robin Hood, industry giant Avalon Hill bought Napoleon at Bay, revised it slightly, and published the second edition in 1983.
In the August–September 1980 issue of Moves (#52), Ian Chadwick called this game "a major breakthrough in dealing with operational levels of Napoleonic campaigns."
