The first President of the Republic of Indonesia, Ir. Soekarno, once advised the Indonesian people, "Never Forget The History (Red Coat)”. This message certainly has a deep meaning so that the Indonesian nation will respect and honor its heroes who died and sacrificed in gaining independence from colonialism. Studying history is important for the nation's future generations, so that they love their homeland, are proud and have a high sense of nationalism. The lack of literature on the history of the nation's struggle is one of the obstacles for researchers and academics in exploring more deeply the heroic stories of heroes that can be used as lessons in filling independence. Scientifically, the history of the nation's struggle must be explained based on the rules of ontology, epistemology and axiology, so that the study of a history can be scientifically justified. The purpose of this research is to analyze the implementation of the implementation of the universal war strategy at the time of the "Battle of Palagan Ambarawa", and how the government's efforts to increase the love of the homeland of the young generation of the nation in filling independence, as well as meeting the limitations of literature on the history of the nation's struggle. The method used in this study uses historical methodology by carrying out four stages of activities, namely, Heuristic, Criticism, Interpretation and Presentation of the synthesis in the form of a story. From the results of research and historical tracing based on secondary data sources, it was found that the "Battle of Palagan Ambarawa" had implemented a universal war strategy, so it could be concluded that the elements of democracy, universality and territory in the implementation of the universal war strategy could defend the country's sovereignty. and in order to increase the sense of nationalism and love for the homeland, the young generation of the nation must be given the "Defend the Nation" program, while the constraints on the limitations of literature on the history of the nation's struggle must be met by the government by reproducing historical reading in the world of education through libraries. So that efforts to develop knowledge, historical studies from various aspects of research can fulfill the rules of ontology, epistemology and axiology of science.
