The Battle of Gettysburg was undoubtedly one of the most decisive battles of the American Civil War and lasted 3 days. This battle was very interesting to simulate, not only because of its importance, but because it was fought at a field which gave many tactical opportunities.

Historically, the Union claimed victory, but both sides suffered similar numbers of casualties. However, the strategic and political cost for the Confederates was larger due to a shortage in manpower and resources.

In Ultimate General: Gettysburg, there is an opportunity for the Confederates to decisively win the battle. Arguably, the battle would have taken a completely different course had Ewell tried to take Cemetery Hill on the first day. The game offers such opportunities to the player for both sides.

There is no pre-determined way to play. Forces arrive from historical directions, but can be delayed or arrive sooner. The first engagement where Buford attempts to delay the Confederates' advance plays a big role in how the battle will escalate, as an opening move does in chess. The next battle scenario is defined depending on key objectives secured and casualties, condition and disposition of units are recorded and transferred as well.
