左宗棠在镇压太平天国革命和陕甘回族人民反抗满清反动统治的斗争中曾起过极坏的作用,但在抵御沙俄入侵,收复新疆的作战中,又起过积极的作用。左宗棠积三十多年军事斗争的经验,特别强调“慎战”的思想,他说:“慎之一字,战之本也”。今天我们研究他的这一作战思想,诸如不轻兵冒进,重视后方安全和后勤保障等,仍然是有借鉴作用的。 Zuo Zongtang had played a very bad role in suppressing the Taiping Rebellion and the Hui people of the Shaanxi and Gansu against the Manchu reactionary rule. However, Zuo Zongtang played a very active role in resisting the invasion by Russia and recovering Xinjiang. Zuo Zongtang plotted over 30 years of military struggle experience, with particular emphasis on the idea of ​​“careful warfare.” He said: “The word of caution and the essence of war are also”. Today, it is still useful for us to study his thinking on this warfare, such as not taking any light-offs and attaching importance to rear-security and logistics support.
