Sardinia Command, 56-55 BC
Appius' command in Sardinia was uneventful, and he was succeeded there in 55 by Marcus Aemilius Scaurus (II).
On the other hand he was politically engaged before and after, attending the packed conferences at Ravenna and Lucca in spring 56 when Julius Caesar patched up the tattered coalition with Crassus and Pompey, and in about summer 55 marrying his younger daughter to Pompeius' homonymous eldest son Gnaeus Pompeius (born ca.79 BC), thus ensuring his election to the consulate for the following year.
