19世纪50年代,俄国逐步侵占清朝黑龙江以北、乌苏里江以东地区一百万平方公里的领土。在入侵过程中,俄国多次试探性的闯入松花江口,企图侵占松花江腹地的领土。为了阻止俄国进一步的侵略野心,清朝驻守黑龙江沿岸卡伦守卡官兵,在吉林将军及三姓副都统的指挥下进行抵抗,两次迫使俄国入侵者退出松花江,有力的维护了松花江腹地的领土安全。 In the 1850s, Russia gradually invaded and occupied one million square kilometers of territory north of Heilongjiang and east of the Ussuri River in the Qing Dynasty. During the invasion, Russia tentatively broke into the mouth of the Songhua River in an attempt to encroach on the territory of the hinterland of the Songhua River. In order to prevent Russia from further invading ambitions, the Qing Dynasty stationed in the Karen Gate officers and soldiers along the coast of Heilongjiang Province, under the command of the generals of Jilin and Sanxingdui Dudu, both forcing the Russian invaders out of the Songhua River and effectively safeguarding the hinterland of the Songhua River Territorial security.
