在艾森河战役（1914年9月12日至15日）期间，当德国人和盟国都开始挖掘战壕时，第一次世界大战的特点完全改变。
盟军在马恩河战役中取得的成功结束了德军在法国的推进，此后德军一直在稳步撤退。 到9月中旬，盟军已经接近艾森河。
陆军元帅约翰-弗伦奇爵士决定派部队过河，然而他无从得知德军是否仍在撤退。
事实上，德军已经沿着Chemin des Dames山脊挖好了浅浅的战壕。 当弗伦奇派人攻打德军阵地时，他们一次又一次地被震耳欲聋的机枪和炮火的轰击所击倒。
1914年9月之前一直是第一次世界大战特点的机动战，在第一次艾森河战役中血腥地结束了。

英国士兵使用他们能找到的任何工具，从附近的农场拿铲子，在某些情况下，甚至用手挖土。
他们不可能知道这些浅坑很快就会延伸到西线的长度，也不可能知道双方会在接下来的3年里占据这些浅坑。
