The Grebbe Line ran from the ''Grebbeberg'' in Rhenen northwards until the IJsselmeer. == Early history and first decommissioning== The Grebbe Line was first established in 1745 as a line of defense to protect the Netherlands from invading armies. If an invasion was imminent, parts of the area between Spakenburg and the Grebbeberg were to be flooded. Until World War II it was never actually used for this purpose; an attempt was made in 1794 to establish a defensive line against the invading French army under General Jean-Charles Pichegru, but the joint English-Dutch army abandoned the line when the French troops approached. Throughout the 19th century the Grebbe line was maintained as a defensive line. However since no attacks appeared likely it was deemed less necessary to maintain the costly fortifications, and in 1926 a large part of the fortifications was decommissioned. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Grebbe line」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
