The tactic used by the archipelago fleet is described as being derived from the theoretical writings of Fredrik Henrik af Chapman, and as developed adjacent to the innovations in naval architecture. This dissertation, however, argues that this may not capture the entirety of the historical truth. The influence of French naval frameworks within the Swedish naval academics could have influenced the practical application of tactics. By delving into the events of the archipelago fleet’s foremost display of tactics, the 1790 Battle of Svensksund, this dissertation aims to determine the actual origin of the tactics. Both French and Swedish theoretical frameworks will be broken down using the concepts of ”ideal types” and then later applied to a chronological depiction of the battle. The results demonstrate that the archipelago fleet did deploy the tactic of af Chapman during the 1790 Battle of Svensksund. Yet, during the movements and preparations prior to the battle, influences from alternate frameworks can be identified. Additionally, the dissertation concludes that af Chapmans tactic was not revolutionary but was rather built upon the previous tactical thought. Thus, the dissertation demonstrates the challenge of pinpointing the origin of a specific tactic, by demonstrating the similarity and correlation between different frameworks.
