Events

Summer – King Charlemagne and his uncle Bernard, son of Charles Martel, crosses with a Frankish expeditionary force the Alps at request of pope Adrian I. At the foot of the mountains in the Susa Valley (Northern Italy) the Franks are hindered by Lombard fortifications. After scouting, Charlemagne attacks the defenders from the flank and forces the Lombards to flee to the fortified capital Pavia.
Siege of Pavia: Charlemagne besieges Pavia which is poorly stocked with food. King Desiderius remains in the capital, he orders his son Adalgis to defend Verona to guard over Gerberga and the children of Carloman I. After a short siege, Adalgis flees to Constantinople where he is received by emperor Constantine V. Meanwhile the Franks capture the cities of Verona and Mortara (Lombardy).
Saxon Wars: Saxon forces seize upon Charlemagne's preoccupation with Italy to retake Eresburg and Syburg (near Dortmund). They unsuccessfully attack the episcopal centre of Büraburg which has been established by St. Boniface (see 723).^[1]
