南口大战前,国民军一军内部产生严重矛盾斗争。冯玉祥的“下野”使其日益剧烈、复杂,最终几至内部发生火并。这是国民军军阀武装本质的充分表现,也是其在华北失败的原因之一,并暴露了本身缺乏政治经济凝聚力的弊端。 Before the south port wars, there was a serious contradiction struggle within the ranks of the First National Army. Feng Yuxiang’s “Under the Hood” made it increasingly violent and complex, with the result that its internal fires would eventually take place. This is a full manifestation of the armed nature of the Kuomintang warlords and one of the reasons why they failed in north China and exposed their own lack of political and economic cohesion.
