13. The Indian Ocean Blockade (Blockade of India, WWII)
Between 1942 and 1945, Japan conducted a submarine campaign in the Indian Ocean aimed at severing Allied supply routes vital for transporting troops and resources between Africa, the Middle East, and Asia. This strategy targeted merchant convoys and naval vessels, seeking to disrupt the movement of essential materials and reinforcements. The campaign’s success posed a significant threat to Allied operations, highlighting the strategic importance of the Indian Ocean during World War II (navyhistory.org).
