留克特拉战役，是一场前371年爆发于底比斯和斯巴达之间的一场战争。在这场战斗在伊巴密浓达首创斜线式战术。 当时针对希腊重步兵方阵一线平推平均分布兵力的特点，其无法在不将列数减少的情况下排出与斯巴达军相同长度的阵形，伊巴密浓达放弃尝试排出与斯巴达相同长度阵形，集中兵力于一翼，改为将左翼的列数增多，由传统的八至十二列改为五十列，力求获得突破。但是有强就有弱，如果自己加强的一侧获得胜利，而削弱的一侧被对方突破，仍然是没有意义的。所以为了保护自己受到削弱的一翼，就把它向后回缩并延迟战斗，尽量拖延它与敌人接触的时间，其加强了的左翼则以双倍速度冲向斯巴达军，希望加强的一翼能够求得决定性的突破。就在这一战，他用这战阵击败了斯巴达精锐部队。 最终底比斯胜利。

The Battle of Leuctra (Greek: Λεῦκτρα, Leûktra) was a battle fought on July 6, 371 BC, between the Boeotians led by Thebans and the Spartans along with their allies amidst the post-Corinthian War conflict. The battle took place in the neighbourhood of Leuctra, a village in Boeotia in the territory of Thespiae. The Theban victory shattered Sparta’s immense influence over the Greek peninsula which Sparta had gained since its victory in the Peloponnesian War.
