“康乾盛世”之时,清朝曾经拥有世界上最为强大的武装力量。比如康熙年间的中俄雅克萨战役,当时康熙派清军3000余人进抵雅克萨城下,将城围困起来,勒令沙俄侵略军投降,对方不理。1686年8月,清军开始攻城,后考虑到沙俄侵略者死守雅克萨,必待援兵,且考虑到隆冬冰合后,舰船行动、马匹粮秣等不便,于是在雅克萨城的南、北、东三面掘壕围困,在城西河上派战舰巡逻,切断守敌外援。 At the time of the “Kangxi and Heyday”, the Qing Dynasty once had the most powerful armed forces in the world. For example, during the Kangxi War in China and Russia, when Kangxi sent more than 3,000 Qing troops to reach the city of Jaen, the city was besieged and the Russians were ordered to surrender their invading forces. In August 1686, when the Qing army began to siege, taking into consideration that the tsarist Russian invaders were sticking with Jacques, they were bound to reinforce the army and, taking into account the inconvenience of the operation of the ships and the horses, North and East three sides digging siege, in the West River to send battleship patrol, cut off enemy defenses.
