Battle of Bali Strait

Dutch and Allied forces arrived in Indonesia on March 2, 1946, with the objective of reclaiming control over Java. Before advancing to Java, they landed on smaller islands, including Bali and the Lesser Sunda Islands. The Dutch rapidly established their presence in these areas, deploying additional troops to strengthen their occupation, eventually amassing a force of 2,000 soldiers in Bali. This escalating threat prompted urgent action from the main base of the Indonesian military in Yogyakarta.^[5] Orders were issued to initiate operations in Java and Bali to safeguard Indonesia's independence from colonial forces. To execute these operations, three key units were mobilized: the M Force under the command of Captain Markadi, Captain Albert Warokka's forces in Banyuwangi, and the Indonesian troops in Bali led by Lieutenant Colonel I Gusti Ngurah Rai. Of these units, Captain Markadi's forces were chosen to lead the operation. Markadi strategically divided his forces into four divisions, assigning three divisions to engage in direct combat and one division to focus on intelligence gathering.^[5][6]

Once the forces were prepared, they launched the operation and attempted to break through the Dutch naval blockade. However, heavy rain hindered their movements, making it difficult to launch an effective assault. During this mission, two Indonesian ships narrowly avoided detection by the Dutch Navy. To evade suspicion, Captain Markadi ordered his crew to disguise themselves as fishermen, a tactic meant to distract the Dutch. As a Dutch Landing Craft Mechanized (LCM) approached their ships, Markadi resorted to a bold strategy: he submerged himself in the water armed with grenades. The Dutch responded with machine gun fire, but their weapons proved ineffective against the Indonesian ships. Taking advantage of this, Markadi and his forces hurled grenades at the Dutch LCM, setting it ablaze and causing significant damage. The battle resulted in light casualties for the Indonesian forces, while the Dutch suffered four fatalities, with their LCMs burned. Following this encounter, Markadi and his troops joined forces with Lieutenant Colonel I Gusti Ngurah Rai's unit in Bali. Their arrival was met with a warm and enthusiastic reception from both local civilians and soldiers.^{[7][8][9][10]}
