March on Vilnius
Vilnius, LithuaniaOn June 28, Napoleon entered Vilnius with only light skirmishing. The foraging in Lithuania proved hard as the land was mostly barren and forested. The supplies of forage were less than that of Poland, and two days of forced marching made a bad supply situation worse. Central to the problem were the expanding distances to supply magazines and the fact that no supply wagon could keep up with a forced marched infantry column.
