1925年11月底,奉军将领郭松龄率领约六万人,从山海关出发,进军沈阳,企图推翻张作霖及奉系军阀在东三省的统治。郭军初期进展顺利,先突破山海关,后于12月5日在连山击溃吉林军。当关内不少议论认为张作霖大势已去时,郭军却在12月22~24日于辽河附近战败,郭松龄及其夫人韩淑秀更被捕杀。日本关东军对郭军的阻挠及对张作霖有形无形的援助,一向被视为郭氏失败的原因。本文将以中、日、英等国的已有史料和新发现史料为基础,重构并讨论1925年1月至12月期间双方的战略、行动经过及其他军事因素,以求从军事角度重新审视双方胜败原因。本文认为张氏父子的角色、战略与作战法运用、良好的后勤和参谋体系,以及郭军作战计划的缺陷比日本在事变中的角色作用更重要。 At the end of November 1925, General Guo Songling, commanding general of the Grenadines, led about 60,000 people from Shanhaikuan and marched into Shenyang in an attempt to overthrow the rule of Zhang Zuolin and Fengxian warlords in the three northeastern provinces. Guo Jun initial progress smoothly, first breakthrough Shanhaiguan, after December 5 in the mountains beat the Jilin army. When many of the arguments in the customs were that Zhang Zuolin’s general situation was gone, Guo Jun was defeated near the Liaohe River from December 22 to December 24, while Guosongling and his wife Han Shuxiu were even more killed. The obstruction by the Kwantung Army to Guo Jun and the tangible assistance to Zhang Tso-lin have always been seen as the reason for Kuo’s defeat. This article will reconstruct and discuss the strategies, actions and other military factors of both sides from January to December 1925 on the basis of the historical materials and newly discovered historical materials of China, Japan and Britain so as to seek a new military perspective Examining the reasons for both wins and losses. This paper argues that the role of Zhang’s father and son, the use of strategic and operational law, good logistics and staff system, and the flaws in Guo’s combat plan are more important than Japan’s role in the incident.
