Ligny

After the rushing French advance from the previous day that opened the campaign, this strategic crossroads that leads to Ligny became a keystone, as it was the connection between the current allied positions. Blucher planned his stand at Ligny believing his right flank would be reinforced by Wellington’s troops coming from Quatre Bras. And Napoleon, once he discovered that the Prussian army was offering battle, conceived a plan for pinning Blucher's troops until the arrival of reinforcements through the same road in order to destroy the Prussian army (his main goal at that very moment). In his own words "The Prussians have been caught flagrante delicto as they were seeking to join the English".
