In 1815, the Duke of Wellington's forces defeated those of Napoleon at the Battle of Waterloo. The battlefield was so small that Wellington personally visited most parts of it while the battle was taking place. Local farmers actually watched the fighting from a hill nearby. The battle ended after one day. It is difficult to imagine a similar battle today.
Fighting can go on for weeks or even months.
