补充资料:白起
| 白起(?~前257) 中国战国后期军事家。又称公孙起。郿(今陕西眉县东)人。初为秦左庶长,由相国魏冉举荐,任主将攻韩、魏,旋升左更。周赧王二十二年(前 293 )伊阙之战,白起用避实击虚、先弱后强的战法,全歼韩、魏联军24万,因功晋升国尉。次年,再升大良造。此后30余载,屡战获胜,攻取70余城。三十六年,率军数万深入楚地,大破楚军,受封武安君。四十二年,赵、魏联军攻韩华阳(今河南新郑北),白起与客卿胡阳率军救韩,大败联军。斩魏兵13万,将赵军2 万驱入河中淹死。五十五年,秦、赵长平之战,白起针对赵军统帅赵括骄躁轻敌、缺乏实战经验的弱点,予以分割包围,待其饥疲交迫,一举歼灭,史传他坑杀降卒40万。后因触怒昭王,贬之士伍,五十八年十二月被迫自杀。白起戎马一生,勇谋兼备,长于野战进攻,料敌用兵,战必求歼,为秦国统一大业立下功勋。后世多称赞其巧妙用兵,而讥评其杀戮无度。 |
