The siege of Bourges was a Frankish siege of the Aquitanian fortress town of Bourges in 762 during the Aquitanian War. The Frankish army under King Pepin the Short invested the fort with lines of circumvallation, contravallation and siege engines. The walls were breached and the fort taken. Count Chunibert of Bourges swore his loyalty to Pepin along with his Gascon levies and their families. Pepin appointed several counts of his own to garrison the place and the Frankish army went on to besiege Thouars.
