本文对日军于一九四四年入侵黔南后立即撤退的原因作了探讨。认为日军为追歼国民党军队而造成“黔南事变”,当其目的达到后为避免过于前出而造成桂柳态势的弱点,故攻占独山后立即撤退。日军入黔过程中虽遇种种困难,但不是立即撤退的主要原因。 This article explores the reasons why Japanese troops retreated immediately after the invasion of southern Guizhou in 1944. They considered that the “Qiannan Incident” caused by the pursuit of the KMT army by the Japanese army resulted in the retreat immediately after the occupation of Dushan, when the purpose of the project was to avoid the weakness of the situation of Gui Liu in order to avoid over-advance. Although the Japanese army encountered difficulties in its entry into Qian, it was not the main reason for its immediate retreat.
