太平天国定都天京后不久,即受到清军最为严酷的围攻,为了解除这种军事压迫感,洪秀全等果断地分兵北伐,深入敌人的心腹地区,打乱了清军围攻天京的战略部署,从而为太平军的战略反攻赢得了宝贵的时间。虽然北伐军最后由于各种原因而全军覆没,但在当时的形势下,北伐是太平天国的最佳战略行为,也是一种自救措施。 Shortly after the Taiping Heavenly Capital was fixed in Tianjing, Hong Kong was severely besieged by the Qing forces. In order to disarm this kind of military oppression, Hong Xiuquan et al decisively separated the expedition from the northern expedition and penetrated into the conflagration areas of the enemy and disrupted the strategic deployment of the Qing army in the siege of Tianjing. Thus gaining precious time for the Taiping’s strategic counter-offensive. Although the Northern Expeditionary Army was finally annihilated by various reasons, the Northern Expedition was the best strategic act of the Taiping Heavenly Kingdom at that time and a self-help measure as well.
