Heroism has existed in Indonesia even long before the founding of the Republic of Indonesia as a unitary nation. It is proper if monuments of heroism have been set up in all areas known for their historical struggles. But the Battle of Surabaya on November 10, 1945 astonished the world. At the end of World War II many Indonesians believed that independence was imminent. Few realized that it would be another five years of fighting before the country became a fully independent republic. The area around the east Javanese town of Surabaya became the scene of some of the heaviest fighting, and the Battle of Surabaya, which cost the lives of many thousands of Indonesians, became a symbol of resistance to the re-imposition of Dutch colonial rule.Late October 1945, some 6,000 British troops of the 49th Brigade of the 23rd Indian Division under Brigadier General Mallaby, entered Surabaya with orders to organize the recovery of Allied POW, and disarm the surrendering Japanese troops. However, the British also sought to establish complete control of Surabaya, but had underestimated the extent of Indonesian resistance and the numbers they faced. They found themselves up against a force of 20,000 troops of the newly-formed and Japanese trained People’s Security Army (Tentara Keamanan Rakyat), and over 100,000 irregular fighters, all dedicated to the cause of Indonesian independence.Fierce fighting broke out on 28 October, and soon the Indonesians had surrounded the British command posts scattered throughout the city. A truce was reached on 30 October, but as evacuations to the harbor area was arranged, in the excitement and confusion, more fighting erupted during which Brigadier General Mallaby was killed. The British then decided to take Surabaya by force, and secretly landed 24,000 troops of the battle-hardened 5th Division from Malaysia, with Sherman medium tanks, backed by naval and air support.
This heavy battle proved that every inch of Indonesia would be defended with blood if necessary. Surabaya was not the only example. Fierce battle broke throughout the archipelago, from Aceh in the west, to Papua in the east. Indonesia will never ever be scared of how advanced you are in military technology, sovereignity is HARGA MATI, dead end.
