"Knights of Malta, 1523-1798" by Reuben Cohen is a historical account written in the early 20th century that chronicles the history of the Knights of St. John of Jerusalem from their settlement in Malta until their fall at the hands of Napoleon. The book details the adventures and struggles of the Knights during a crucial period in Mediterranean history, focusing on their military confrontations with the Ottoman Empire, particularly the notable Siege of Malta in 1565. The narrative unfolds through five main chapters, beginning with the Knights' departure from Rhodes and their subsequent efforts to fortify and defend Malta. Cohen vividly describes the intense siege led by the Ottomans and the valor of the Knights under Grand Master Jean Parisot de la Valette. As the story progresses, the book addresses the Order's decline due to internal conflicts and external pressures, painting a picture of the Knights transitioning from powerful defenders of Christendom to a disintegrating organization by the end of the 18th century. The final chapters detail the impact of the French Revolution on the Knights and culminate in their eventual surrender to Napoleon in 1798, marking a significant moment in both Maltese and European history.
