Bari

In his efforts to restore order in Italy, Louis met with considerable success both against Italy's turbulent princes and against the

s who were ravaging southern Italy. In 866, after issuing a call for assistance to fight the

s, he routed these invaders, but could not follow up his successes owing to the lack of a fleet. So in 869 he made alliance with the eastern emperor, Basil I, who sent him ships to assist in the capture of Bari, capital of the Emirate of Bari, which succumbed in 871. Meanwhile, his brother Lothair had died in 869, and owing to his detention in southern Italy, Louis failed to prevent the partition of Lotharingia between Louis the German and Charles the Bald. Some jealousy between Louis and Basil followed the victory at Bari, and in reply to an insult from the eastern emperor Louis attempted to justify his right to the title "emperor of the Romans."

Benevento

He had withdrawn into Benevento to prepare for a further campaign when he was treacherously attacked in his palace, robbed and imprisoned by Adelchis, prince of Benevento, in August 871. The capture of Louis was lamented in a contemporary short poem, the '' Rythmus de captivitate Ludovici imperatoris''. The landing of fresh bands of Saracens compelled Adelchis to release his prisoner a month later, and Louis was forced to swear he would take no revenge for this injury, nor ever enter Benevento with an army. Returning to Rome, he was released from his oath, and was crowned a second time as emperor by Pope Adrian II on 18 May 872. Then Louis won further successes against the Saracens, relieving the siege of Salerno and driving them from Capua, but the emperor's attempts to punish Adelchis were not very successful. Returning to northern Italy, he died, near
