Sikelgaita (also Sichelgaita or Sigelgaita) (1040 – 16 April 1090) was a Lombard princess, the daughter of Prince Guaimar IV of Salerno and second wife of Duke Robert Guiscard of Apulia. She commanded troops in her own right. Life She married Robert in 1058, after Robert divorced his first wife Alberada, due to supposed consanguinity. Her sister Gaitelgrima had earlier married Robert's half-brother Drogo. The divorce from Alberada and the marriage to Sikelgaita were probably part of a strategy of alliance with the remaining Lombard princes, of whom Guaimar was chief. Alberada, for her part, appears to have had no qualms about dissolving her marriage. Sikelgaita tried to mediate between her brother Gisulf II of Salerno and husband when their relations went sour, but her pleas went unheeded and she accepted her brother's lot in the war with Guiscard (1078). Sikelgaita frequently accompanied Robert on his conquests. She conducted the siege of Trani (1080) while Robert moved against Taranto. Although at first she tried to persuade him not to attack the Byzantine Empire, she nevertheless brought troops and accompanied him on his campaign against them. At the Battle of Dyrrhachium in 1081 she was on the field in full armour, rallying her and Robert's troops when they were initially repulsed by the Byzantine army and were in danger of losing cohesion. According to the Byzantine historian Anna Comnena, she was "like another Pallas, if not a second Athena," and, in the Alexiad, Anna attributes to her a quote from the Iliad. John Julius Norwich wrote: "in her we come face to face with the closest approximation in history to a Valkyrie. A woman of immense build and herculean physical strength, she hardly ever left her husband's side – least of all in battle, one of her favourite occupations. At such moments, charging magnificently into the fray, her long blond hair streaming out from beneath her helmet, deafening friend and foe alike with huge shouts of encouragement or imprecation, she must have looked – even if she did not altogether sound – worthy to take her place among the daughters of Wotan." In 1083, Sikelgaita returned to Italy with Robert to defend Pope Gregory VII against the Emperor Henry IV. She accompanied him on a second campaign against the Byzantines, during which Robert died on Kefalonia in 1085 with Sikelgaita at his side. Early in 1086, Sikelgaita was in Salerno making
