几世纪来,人们都熟知英格兰东南部是不列颠帝国政治、经济和文化中心。它在军略上的地位可以一言以蔽之,曰:不可攻破的。九百年来,除了获得英国人的内应以外,没有一个侵入者曾经打通过它的堡垒——英吉利海峡——而在英国领土上建立根据地。但在一○六六年,日耳曼威廉王曾运载骑兵,通过索姆湾,侵入内地,并征服了英国。自此以后,这一带海岸曾有三次受到侵入军队的严重威胁。 For centuries, it was well known that southeast England was the political, economic and cultural center of the British Empire. Its position on the military strategy can be summed up in a word, saying: Can not be broken. For nine hundred years, none of the intruders had fought through its fort, the English Channel, in addition to gaining the British domestic remedy, while establishing bases on British soil. However, in 1066, the Germanic William was a cavalry soldier who invaded the interior through Somme Bay and conquered the United Kingdom. Since then there have been three serious threats to the invasion of the coast by the coast.
