多年来学界对刘铭传撤师基隆是否于沪尾大捷有援救作用是有争议的:或认为刘铭传“撤基”没有必要,或认为“撤基”对沪尾大捷有作用。在总结前人观点的基础上,通过分析当时的战场情形,得出刘铭传撤基对于淡水之役有重大的援救作用。 Over the years, there has been controversy over the rescue operation of Liu Ming by the academia on whether or not Liu Ming’s transfer of Chinglon to Shanghai at the end of the war: that there is no need for Liu Ming-chuan or “withdrawal of the base”, or that “withdrawal of the base” will have an effect on the victory of the Shanghai-Shanghai Expressway. On the basis of summarizing the views of our predecessors, by analyzing the situation in the battlefield at the time, we can conclude that Liu Mingchuan’s withdrawal from the base has a major rescuing function for the Battle of the Fresh Water.
