The hill where Napoleon watched his army

The hill in question, known as Jiesia (Pajesys) hill fort mound, is located in Kaunas, Lithuania, on the left bank of the Nemunas, between the Panemunė and Railway bridges. It stands at an elevation of 63.3 meters. For centuries, it has been known as Napoleon's hill, a name that has stuck since the 19th century.

On 23 June 1812, Napoleon Bonaparte arrived at the Nemunas River near Panemunė, where he began reconnoitering the river from Panemunė to Aleksotas. General Jean-Baptiste Eblé led the Grand Army Bridge Construction Unit. He was ordered to build three bridges across the Nemunas, 300 metres apart.

According to the orders, two of the bridges were to be built between the Panemunė and the Jiesia river, and one was to be built to the left of the river, opposite the hill from which the Emperor chose to command the crossing. From this height, Napoleon watched his Grande Armée cross the Neman during the French invasion of Russia on 24/25 June 1812.
