In 929, with Atenulf II, Guaimar II, and Theobald of Spoleto, he invaded Apulia and Calabria again. This time, all were unsuccessful and Theobald hurt the old alliance. In 933, Landulf associated his son Atenulf with himself and his brother in the government. In 934, Guaimar was persuaded to quit the alliance by the Byzantine agent Cosmas of Thessalonica. In 935, King Hugh of Italy gave his support to the Greeks. Within a few years, Landulf's successful anti-Byzantine policy had been reversed and he was forced to make peace, but clashes continued: at Siponto in 936 and at Matera in 940. In 937, a band of Hungarians marched from Burgundy to Italy via the Rhone valley in the service of King Hugh, who sent them against Monte Cassino, Naples and Capua, plundering and destroying all before them. In 939, Landulf's brother Atenulf died and Atenulf's eldest son, Landulf, succeeded him, but was soon exiled to Naples by his uncle. He died four years later on April 10, 943.
