The Battle of Bull Run took place in July 1861 and although when all was said and done, its impact was relatively limited, it did have a far-reaching effect on the American Civil War itself. The psychological impact of the battle on the combatants was indeed unquestionable, particularly for the North, and increased general consciousness of the reality of war and the challenges that lay ahead. The first Battle of Manassas was special because it was the first large-scale engagement in which troops were brought to the battle area by train, which enabled the Confederates to win this battle.Author Pascal le Pautremat has a doctorate in contemporary history; he is a lecturer in geopolitics and is a specialist of modern conflicts and crisis.
