The Battle of Arras was a British offensive during World War I. From 9 April to 16 May, 1917, British, Canadian, and Australian troops attacked German trenches near the French city of Arras on the Western Front. The Arras offensive was conceived as part of a plan to break through the German defences into the open ground beyond and engage the numerically inferior German army in a war of movement. It was planned in conjunction with the French High Command, who were simultaneously embarking on a massive attack (the Nivelle Offensive) about eighty kilometres to the south. The stated aim of this combined operation was to end the war in forty-eight hours. At Arras, the British Empire's immediate objectives were more modest: (1) to draw German troops away from the ground chosen for the French attack and (2) to take the German-held high ground that dominated the plain of Douai. After considerable bombardment, Canadian troops advancing in the north were able to capture the strategically significant Vimy Ridge. Only in the south, where British and Australian forces were frustrated by the elastic defence, were the attackers held to minimal gains. Although these battles were generally successful in achieving limited aims, many of them resulted in relatively large numbers of casualties. (Full article...)

Eadbald was King of Kent from 616 until his death. He succeeded his father Æthelberht, who made Kent the dominant force in England during his reign and became the first Anglo-Saxon king to convert to Christianity. Eadbald's accession was a significant setback for the growth of the church, since he was a pagan and did not convert for at least a year, and perhaps for as much as eight years. He was ultimately converted by either Laurentius or Justus, and separated from his first wife, who had been his stepmother, at the insistence of the church. Eadbald's second wife was Ymme, who may have been a Frankish princess. She bore him two sons, Eormenred and Eorcenberht, and a daughter, Eanswith. Eadbald's influence was less than his father's, but Kent was powerful enough to be omitted from the list of kingdoms dominated by Edwin of Northumbria. Edwin's marriage to Eadbald's sister, Æthelburg, established a good relationship between Kent and Northumbria which appears to have continued into Oswald's reign. When Æthelburg fled to Kent on Edwin's death in about 633, she sent her children to Francia for safety, fearing the intrigues of both Eadbald and Oswald. The Kentish royal line made several strong diplomatic marriages over the succeeding years. (Full article...)
