甘罗列传

    甘罗者,甘茂孙也。茂既死后,甘罗年十二,事秦相文信侯吕不韦。

    秦始皇帝使刚成君蔡泽于燕,三年而燕王喜使太子丹入质于秦。秦使张唐往相燕,欲与燕共伐赵,以广河间之地。张唐谓文信侯曰:“臣尝为秦昭王伐赵,赵怨臣,曰:‘得唐者与百里之地。’今之燕必经赵,臣不可以行。”文信侯不快,未有以强也。甘罗曰:“君侯何不快之甚也?”文信侯曰:“吾令刚成君蔡泽事燕三年,燕太子丹已入质矣,吾自请张卿相燕而不肯行。”甘罗曰:“臣请行之。”文信侯叱曰:“去!我身自请之而不肯,女焉能行之?”甘罗曰:“大项橐生七岁为孔子师。今臣生十二岁于兹矣,君其试臣,何遽叱乎?”

    于是甘罗见张卿曰:“卿之功孰与武安君?”卿曰:“武安君南挫强楚,北威燕、赵,战胜攻取,破城堕邑,不知其数,臣之功不如也。”甘罗曰:“应侯之用于秦也,孰与文信侯专?”张卿曰:“应侯不如文信侯专。”甘罗曰:“卿明知其不如文信侯专与?”曰:“知之。”甘罗曰:“应侯欲攻赵,武安君难之,去咸阳七里而立死于杜邮。今文信侯自请卿相燕而不肯行,臣不知卿所死处矣。”张唐曰:“请因孺子行。”令装治行。

    行有日,甘罗谓文信侯曰:“借臣车五,请为张唐先报赵。”文信侯乃入言之于始皇曰:“昔日茂之孙甘罗,年少耳,然名家之子孙,诸侯皆闻之。今者张唐欲称疾不肯行,甘罗说而行之。今愿先报赵,请许遣之。”始皇召见,使甘罗于赵。赵襄王郊迎甘罗。甘罗说赵王曰:“王闻燕太子丹入质秦欤?”曰:“闻之。”曰:“闻张唐相燕欤?”曰:“闻之。”“燕太子丹入秦者,燕不欺秦也。张唐相燕者,秦不欺燕也。燕、秦不相欺者,伐赵,危矣。燕、秦不相欺,无异故,欲攻赵而广河间。王不如赍臣五城以广河间,请归燕太子,与强赵攻弱燕。”赵王立自割五城以广河间。秦归燕太子。赵攻燕,得上谷三十城,令秦有十一。

    甘罗还报秦,乃封甘罗以为上卿,复以始甘茂田宅赐之。

    太史公曰甘罗年少然出一奇计声称后世虽非笃行之君子然亦战国之策士也方秦之强时天下尤趋谋诈哉
