He was the son of
Hugh II, Count of Maine and succeeded his father as Count of Maine He constructed the fortress at
Sablé but by 1015 it ended up being held by the viscounts of Maine. He was a supporter of
Richard II, Duke of Normandy. Allied with
Odo II, Count of Blois, he fought against the kings
Hugh Capet and
Robert II of France, but he was forced to acknowledge the
Count of Anjou as his
suzerain. During the siege of
Tillières, Hugh narrowly escaped from the Norman forces pursuing him by disguising himself as a local shepherd. Throughout the tenth century the dynasty of counts of Maine, of which Hugh III, his father Hugh II, and grandfather Hugh I were all members struggled to control both the city of
Le Mans and church
investitures and in that effort were in near constant warfare with the Bishops of Le Mans, notably Segenfridus and
Avesgaudus. Between 995 and 1015 Hugh III donated several properties including four
vineyards and three mills in Le Mans to the monks of
Mont Saint-Michel In
Normandy. When approached by Abbot Hildebert in 1014 in requesting more land in the area of Le Mans, Hugh III generously gave the land of
Voivres and personally placed the offering on the altar at Mont Saint-Michel. Hugh died . ==Issue==
