The Battle of 
Surabaya was fought between pro-independence Indonesian soldiers and militia 
against British and Dutch troops as a part of the Indonesian National Revolution. 
The peak of the battle was in November 1945. Despite fierce resistance, British 
Indian troops managed to conquer Surabaya, the second-largest city in Indonesia, on 
behalf of the Netherlands. The battle was the heaviest single battle of the 
revolution and became a national symbol of Indonesian resistance. Considered a heroic effort by Indonesians, the battle helped galvanise 
Indonesian and international support for Indonesian independence. 10 November is 
celebrated annually as Heroes' Day (Hari Pahlawan).
By the time the Allied 
forces arrived at the end of October 1945, the pemuda ('youth') 
foothold in Surabaya City was described as "a strong unified fortress". Ferocious fighting erupted when 6,000 Indian troops landed in the city to 
evacuate European internees. Following the killing on 30 October of the British 
commander, Brigadier A. W. S. Mallaby, the 
British retaliated with a punitive sweep that began on 10 November, under the 
cover of air attacks. Although the European forces largely captured the city in 
three days, the poorly armed Republicans fought for three weeks, and thousands 
died as the population fled to the countryside.
Despite the military 
defeat suffered by the Republicans and a loss of manpower and weaponry that 
would severely hamper Republican forces for the rest of the revolution, the 
battle and defence mounted by the Indonesians galvanised the nation in support 
of independence and helped garner international attention. For the Dutch, it 
removed any doubt that the Republic was not simply a gang of collaborators 
without popular support. It also had the effect of convincing Britain that 
wisdom lay on the side of neutrality in the revolution; within a few years, in fact, Britain would support the Republican cause in the 
United Nations
Death of Brigadier Mallaby
On 30 October 1945, 
Brigadier A. W. S. Mallaby, the British 
brigade commander in Surabaya, was travelling about Surabaya to spread the news 
about the new agreement to his troops. When his car approached the British 
troops' post in the International building near the Jembatan Merah ("Red 
Bridge"), his car was surrounded by Indonesian Republican militia. Shortly 
after, Mallaby was shot and killed by the militia under confused 
circumstances.
Captain R.C. Smith, 
who was in the stationary car, reported that a young Republican shot and killed 
Mallaby after a short conversation. Smith then reported throwing a grenade from 
the car in the direction of where he thought the shooter had hidden. Although he 
was not sure whether or not it hit its target, the explosion caused the back 
seat of the car to ignite. Other accounts, according to the same source, stated that it was the explosion and not a shooter that killed Mallaby. 
Regardless of its exact details, Mallaby's death was a significant turning point 
for the hostilities in Surabaya, and a catalyst for the battle to come. The 
British ordered an Indonesian surrender, and on 10 November they rolled out a 
large retaliatory attack
Linggadjati Agreement
The Linggadjati 
Agreement, brokered by the British and concluded in November 1946, saw the 
Netherlands recognise the Republic as the de facto authority over Java, 
Madura, and Sumatra. 
Both parties agreed to the formation of the United States of Indonesia by 1 
January 1949, a semi-autonomous federal state with the monarch of the Netherlands at its 
head. The Republican-controlled Java and Sumatra would be one of its states, 
alongside areas that were generally under stronger Dutch influence, including 
southern Kalimantan, and the "Great East", which consisted of Sulawesi, Maluku, 
the Lesser 
Sunda Islands, and Western New Guinea. The Central National 
Committee of Indonesia (KNIP) did not ratify the agreement until February 1947, 
and neither the Republic nor the Dutch were satisfied with it.[2] On 25 
March 1947 the Lower House 
of the Dutch parliament ratified a stripped down version of the treaty, which 
was not accepted by the Republic.[34] Both 
sides soon accused the other of violating the agreement
[edit] Renville Agreement
Main article: Renville 
Agreement
The United Nations 
Security Council brokered the Renville Agreement in an attempt to rectify the 
collapsed Linggarjati Agreement. The agreement was ratified in January 1948 and 
recognised a cease-fire along the so-called 'Van Mook line'; an 
artificial line which connected the most advanced Dutch positions.[38] Many 
Republican positions, however, were still held behind the Dutch lines. The 
agreement also required referenda to be held on the political future of the 
Dutch held areas. The apparent reasonableness of Republicans garnered much 
important American goodwill.
Diplomatic efforts 
between the Netherlands and the Republic continued throughout 1948 and 1949. 
Political pressures, both domestic and international, hindered Dutch attempts at 
goal formulation. Similarly Republican leaders faced great difficulty in 
persuading their people to accept diplomatic concessions. By July 1948 
negotiations were in deadlock and the Netherlands pushed unilaterally towards 
Van Mook’s federal Indonesia concept. The new federal states of South Sumatra 
and East Java were created, although neither had a viable support base. The Netherlands 
set up the Bijeenkomst voor Federaal Overleg (BFO) (or Federal Consultative Assembly), a 
body comprising the leadership of the federal states, and charged with the 
formation of a United States of Indonesia and an 
interim government by the end of 1948. The Dutch plans, however, had no place 
for the Republic unless it accepted a minor role already defined for it. Later 
plans included Java and Sumatra but dropped all mention of the Republic. The 
main sticking point in the negotiations was the balance of power between the 
Netherlands High Representative and the Republican forces.
Mutual distrust between 
the Netherlands and the Republic hindered negotiations. The Republic feared a 
second major Dutch offensive, while the Dutch objected to continued Republican 
activity on the Dutch side of the Renville line. In February 1948 the Siliwangi 
Battalion of the Republican Army, led by Nasution, marched from West Java to Central Java; the 
relocation was intended to ease internal Republican tensions involving the 
Battalion in the Surakarta area. The Battalion, however, clashed with Dutch 
troops while crossing Mount 
Slamet, and the Dutch believed it was part of a systematic troop movement 
across the Renville Line. The fear of such incursions actually succeeding, along 
with apparent Republican undermining of the Dutch-established Pasundan state and 
negative reports, led to the Dutch leadership increasingly seeing itself as 
losing control.
Internal turmoil
Social revolutions
The so-called 'social 
revolutions' following the independence proclamation were challenges to the 
Dutch-established Indonesian social order, and to some extent a result of the 
resentment against Japanese-imposed policies. Across the country, people rose up 
against traditional aristocrats and village heads and attempted to exert popular 
ownership of land and otr resources. The majority of the social revolutions ended quickly; in most cases the 
challenges to the social order were quashed]
A culture of violence 
rooted in the deep conflicts that split the countryside under Dutch rule would 
repeatedly erupt throughout the whole second half of the twentieth century. The term 'social revolution' has been applied to a range of mostly violent 
activities of the left that included both altruistic attempts to organise real 
revolution and simple expressions of revenge, resentment and assertions of 
power. Violence was one of the many lessons learned during the Japanese 
occupation, and figures identified as 'feudal', including kings, regents, or simply the 
wealthy, were often attacked, sometimes beheaded, and rape became a weapon 
against 'feudal' women. In 
the coastal sultanates of Sumatra and Kalimantan, for example, sultans and others whose authority had been shored-up by 
the Dutch, were attacked as soon as Japanese authority left. The secular local 
lords of Aceh, who had been the foundation 
of Dutch rule, were executed, although most of Indonesia's sultanates fell back 
into Dutch hands.
Most Indonesians lived 
in fear and uncertainty, particularly a significant proportion of the population 
who supported the Dutch or who remained under Dutch control. The popular 
revolutionary cry 'Freedom or Death' was often interpreted to justify killings 
under claimed Republican authority. Traders were often in particularly difficult 
positions. On the one hand, they were pressured by Republicans to boycott all 
sales to the Dutch; on the other hand, Dutch police could be merciless in their 
efforts to stamp out smugglers on which the Republican economy depended. In some 
areas, the term kedaulatan rakyat ('exercising the sovereignty of the 
people') – which is mentioned in the preamble of the Constitution and used by 
pemuda to demand pro-active policies from leaders – came to be used not 
only in the demanding of free goods, but also to justify extortion and robbery. 
Chinese merchants, in particular, were often forced to keep their goods at 
artificially low prices under threat of death.
Communist and Islamist insurgencies
Main articles: Madiun Affair and Darul Islam 
(Indonesia)
On 18 September 1948 an 
'Indonesian Soviet 
Republic' was declared in Madiun, east of Yogyakarta, by members of the PKI and 
the Indonesian Socialist Party (PSI). 
Judging the times as right for a proletarian uprising, they intended it to be a 
rallying centre for revolt against "Sukarno-Hatta, the slaves of the Japanese 
and America".[13] 
Madiun however was won back by Republican forces within a few weeks and the 
insurgency leader, Musso, killed. RM Suryo, the 
governor of East Java, several police officers and religious leaders were killed 
by the rebels. This ended a distraction for the revolution, and 
it turned vague American sympathies based on anti-colonial sentiments into 
diplomatic support. Internationally, the Republic was now seen as being 
staunchly anti-communist 
and a potential ally in the emerging global Cold War between the American-led 'free world' and the 
Soviet-led bloc.
Members of the 
Republican Army who had come from Indonesian Hizbullah felt betrayed by 
Indonesian Government. In May 1948, they declared a break-away regime, the 
Negara Islam Indonesia (Indonesian Islamic State), better known as 
Darul Islam. Led by an Islamic mystic, Sekarmadji Maridjan 
Kartosuwirjo, Darul Islam sought to establish Indonesia as an Islamic theocracy. At the 
time, the Republican Government did not respond as they were focused on the 
threat from the Dutch. Some leaders of Masjumi sympathised with the rebellion. After the 
Republic regained all territories in 1950, the government took the Darul 
Islam threat seriously, especially after some provinces declared their 
joining of Darul Islam. The rebellion was put down in 1962.
Transfer of sovereignty
Millions upon millions flooded the sidewalks, the roads. They were crying, cheering, screaming "...Long live Bung Karno..." They clung to the sides of the car, the hood, the running boards. They grabbed at me to kiss my fingers. Soldiers beat a path for me to the topmost step of the big white palace. There I raised both hands high. A stillness swept over the millions. "Alhamdulillah – Thank God," I cried. "We are free"
—Sukarno's recollections of independence achieved.
The resilience of 
Indonesian Republican resistance and active international diplomacy set world 
opinion against the Dutch efforts to re-establish their colony.[46] The 
second 'police action' was a diplomatic disaster for the Dutch cause. The newly 
appointed United States Secretary of 
State Dean Acheson 
pushed the Netherlands government into negotiations earlier recommended by the 
United Nations but until then defied by the Netherlands. The Dutch–Indonesian 
Round Table Conference was held in The Hague from 23 August 1949 to 2 
November 1949 between the Republic, the Netherlands, and the Dutch-created 
federal states. The Netherlands agreed to recognise Indonesian sovereignty over 
a new federal state known as the 'United States of Indonesia' (RUSI). 
It would include all the territory of the former Dutch East Indies with the 
exception of Netherlands New Guinea; sovereignty over 
which it was agreed would be retained by the Netherlands until further 
negotiations with Indonesia. The other difficult issue to which Indonesia gave 
concessions was Netherlands East Indies debt. Indonesia agreed to responsibility 
for this sum of £4.3 billion, much of which was directly attributable to Dutch 
attempts to crush the revolution. Sovereignty was formally transferred on 27 
December 1949, and the new state was immediately recognised by the United States 
of America.
 
 
The United States of Indonesia, December 
1949 – the Republic of Indonesia is shown in red
Republican-controlled 
Java and Sumatra together formed a single state in the sixteen-state RUSI 
federation, but accounted for almost half its population. The other fifteen 
'federal' states had been created by the Netherlands since 1945. These states 
were dissolved into the Republic over the first half of 1950. An abortive 
anti-Republic coup in Bandung and Jakarta by Westerling's Legion of Ratu 
Adil (APRA) on 23 January 1950 resulted in the dissolution of the populous 
Pasundan state in West Java, thus 
quickening the dissolution of the federal structure. Colonial soldiers, who were 
largely Ambonese, clashed with Republican troops in Makassar during the Makassar Uprising in April 1950. The 
predominantly Christian Ambonese were from one of the few regions with pro-Dutch 
sentiments and they were suspicious of the Javanese Muslim-dominated Republic, 
whom they unfavourably regarded as leftists. On 25 April 1950, an independent Republic 
of South Maluku (RMS) was proclaimed in Ambon but this was suppressed by 
Republican troops during a campaign from July to November. With the state of 
East Sumatra now being the only federal state remaining, it too folded and fell 
in line with the unitary Republic. On 17 August 1950, the fifth anniversary of 
his declaration of Indonesian independence, Sukarno proclaimed the Republic of Indonesia as a unitary state.
Impacts
Although there is no 
accurate account of how many Indonesians died, they died in far greater numbers 
than their enemies, and many died at the hands of other Indonesians. Estimates 
of Indonesian deaths in fighting range from 45,000 to 100,000 and civilian 
casualties exceeded 25,000 and may have been as high as 100,000. A 
total of 1,200 British soldiers were killed or went missing in Java and Sumatra 
in 1945 and 1946, most of them Indian soldiers. More than 5,000 
Dutch soldiers lost their lives in Indonesia between 1945 and 1949. Many more 
Japanese died; in Bandung alone, 1,057 died, only half of whom died in actual 
combat, the rest killed in rampages by Indonesians. Tens of thousands of Chinese 
and Eurasians were killed or left homeless, despite the fact that many Chinese 
supported the revolution. Seven million people were displaced on Java and 
Sumatra.
The revolution had 
direct effects on economic conditions; shortages were common, particularly food, 
clothing and fuel. There were in effect two economies – the Dutch and the 
Republican – both of which had to simultaneously rebuild after World War II and 
survive the disruptions of the revolution. The Republic had to set up all 
necessities of life, ranging from 'postage stamps, army badges, and train 
tickets' whilst subject to Dutch trade blockades. Confusion and ruinous 
inflationary surges resulted from competing currencies; Japanese, new Dutch 
money, and Republican currencies were all used, often concurrently.
Indonesian independence 
was secured through a blend of both diplomacy and force. Despite their 
ill-discipline raising the prospect of anarchy, without pemuda 
confronting foreign and Indonesian colonial forces, Republican diplomatic 
efforts would have been futile. The revolution is the turning point of modern Indonesian 
history, and it has provided the reference point and validation for the 
country’s major political trends that continue to the present day. It gave 
impetus to communism in the country, to militant nationalism, to Sukarno's 'guided democracy', to 
political Islam, the origins of the Indonesian army and its role in Indonesian 
power, the country's constitutional arrangements, and the centralism of power in 
Indonesia.
The revolution 
destroyed a colonial administration ruled from the other side of the world, and 
dismantled with it the raja, seen by many as obsolete and powerless. 
Also, it relaxed the rigid racial and social categorisations of colonial 
Indonesia. Tremendous energies and aspirations were created amongst Indonesians; 
a new creative surge was seen in writing and art, as was a great demand for 
education and modernisation. It did not, however, significantly improve the 
economic or political fortune of the population’s poverty-stricken peasant 
majority; only a few Indonesians were able to gain a larger role in commerce, 
and hopes for democracy were dashed within a decade
