Tense and gripping. The sound of gunfire and bomb explosions echoed from north to south in Dukuh Plataran, Selomartani Village, Yogyakarta, on Monday morning, February 24, 2025. In the north, Dutch soldiers carried ammunition, and machine guns, and drove jeeps. Meanwhile, in the south, Indonesian troops armed with rifles and machine guns stood ready.
Dust and smoke—reducing visibility—accompanied the deafening gunfire. Some Indonesian fighters fell in battle, but their sacrifice only fueled the determination and spirit of their comrades. With heroic resilience, they managed to repel the Dutch troops.
Thus ended the Socio-Drama of the Battle of Plataran 1949, performed by the youth of Plataran that morning. The drama vividly depicted the intense battle that took place 76 years ago between the guerrilla forces of the Yogyakarta Military Academy (MA Yogya) and the Dutch Army’s Battalion 1, Infantry Regiment 5, of the Royal Netherlands Army. The MA Yogya guerrillas successfully pushed back the Dutch forces after a series of dramatic engagements. But what was the actual chronology of the battle?
According to Prof. Dr. Ir. Indroyono Soesilo, MSc, a member of the Advisory Board of the Yogyakarta Military Academy Alumni Association (IKAM Yogya), the history of the Battle of Plataran began on Sunday, December 19, 1948, when the Dutch launched an attack on Yogyakarta. At that time, Yogyakarta was the capital of the Republic of Indonesia. The Dutch offensive was codenamed Operation Kraai or “Operation Raven.”
The operation started with a Dutch paratrooper assault that seized Maguwo Air Base. The Republic’s leaders were then arrested and exiled to Brastagi, North Sumatra, and Bangka Island. The Dutch had betrayed the Renville Agreement, which had been signed on January 17, 1948.
The only institution that did not surrender to the Dutch was the Indonesian National Army (TNI). The Supreme Commander of the TNI, General Soedirman, issued Tactical Order No. 1 of 1948, shifting from conventional warfare—with clear territorial boundaries—to a universal guerrilla warfare strategy. Following this order, all TNI units withdrew from Yogyakarta, including a company of junior officers and cadets from MA Yogya, led by the Governor of MA Yogya, Colonel GPH Jatikusumo. They moved and took positions in the Sleman area, north of Yogyakarta.
The TNI established Wehrkreise III (Resistance Area III), commanded by Lt. Col. Soeharto. The MA Yogya troops were placed in Sub-Wehrkreise 104, with an operational boundary stretching from the Yogya-Solo highway to Kaliurang at the foot of Mount Merapi.
The MA Yogya guerrillas engaged in guerrilla warfare tactics: “If the enemy is off guard, we attack; if reinforcements arrive, we retreat.” They fought at night and hid during the day. They lived among the people, were sheltered by them, and were provided with food and drink.
During the Guerrilla War of 1948–1949, there were 16 recorded battles between the Dutch Army and the MA Yogya guerrillas. Remarkably, the MA Yogya guerrillas were highly skilled in tactics and strategy, earning them the nickname “Elite Troops” (keur-troepen) from the Dutch.
On Tuesday, February 22, 1949, the MA Yogya Guerrilla Headquarters received intelligence about Dutch troops stationed in Sambiroto, about 4 kilometers from Plataran. A squad led by Lt. Sarsono was assigned to monitor Dutch movements in Sambiroto. Ten junior officers and cadets moved toward the location.
A cadet named Abdul Djalil wanted to join the patrol but was forbidden by his commander, as he had just recovered from a gunshot wound sustained in a previous attack on a Dutch headquarters in Yogyakarta. However, without his commander’s knowledge, Cadet Abdul Djalil sneaked in and walked at the back of the formation.
Upon reaching the Sambiroto intersection, the MA guerrillas were unaware that the Dutch soldiers had already positioned themselves with machine guns at the ready. A Dutch soldier shouted, “Wacht Voor?” (“Who’s there?”). Instinctively, Lt. Sarsono shouted back, “Bellandaa…” (Dutch!). Instantly, a hail of Dutch machine-gun fire erupted. The MA guerrillas immediately dropped to the ground and managed to evade the bullets. Lt. Sarsono then counted his men—everyone was safe, Alhamdulillah!
Back at the headquarters, the soldiers asked, “Where is Cadet Abdul Djalil?” It was only then that they realized he had secretly joined the patrol and had fallen under Dutch machine-gun fire. He died as a national hero. Quiet and artistic, Abdul Djalil loved writing in his diary. Unfortunately, the Dutch seized his diary, revealing the location of the MA Yogya guerrilla headquarters, which they had long sought.
Governor MA, Colonel GPH Jatikusumo, immediately relocated the headquarters from Ngrangsang to Gatak. The diary also mentioned a previous headquarters in Kringinan, which was soon bombarded by the Dutch Air Force’s P-51 Mustang “Red Nose” aircraft.
On the night of Wednesday, February 23, 1949, an MA Yogya guerrilla unit called “Platoon Z,” with more than one platoon in strength, moved to Bogem, Prambanan, to attack Dutch outposts.
The following morning, Thursday, February 24, 1949, the guerrillas returned to their headquarters but decided to rest in Plataran before heading back. Unexpectedly, a Dutch company from Battalion 1, Infantry Regiment 5, launched a “cleansing operation” in the area. As they arrived in Gatak, the Dutch began firing at civilians. Dutch forces coming from Gatak and Kaliwaru surrounded the MA guerrilla positions, and an uneven battle ensued. One platoon faced an entire company—a 1-to-3 disadvantage. Additionally, the Dutch deployed small aircraft to drop grenades on the guerrillas below.
Junior Officer Lt. Utoyo Notodirjo, stationed at the MA Yogya guerrilla headquarters, heard the gunfire and immediately rushed to the battlefield. A distinguished officer from MA Yogya’s first class, he served directly under Lt. Col. Soeharto at Wehrkreise III headquarters. That night, he happened to be at the guerrilla base preparing for the March 1 General Offensive.
Lt. Utoyo jumped into battle, organizing the retreat of MA troops. Seeing an injured cadet carrying a Bren machine gun, he took over the weapon and provided cover fire for his troops. Eventually, a Dutch bullet pierced his helmet, and he fell in battle.
The Battle of Plataran ended with eight fallen heroes:
- Lt. Utoyo Notodirjo – Honored as the name of the Obstacle Course Field at the Indonesian Military Academy (AKMIL) in Magelang.
- Lt. Sukoco – Honored as the name of the Swimming Pool at AKMIL in Pisangan.
- Cadet Officer Abdul Jalil – Honored as the name of the AKMIL Museum in Magelang.
- Cadet Officer Suharsojo – Honored as the name of the Chemistry Lab at AKMIL.
- Cadet Officer Subiyakto – Honored as the name of the Data Room at AKMIL.
- Cadet Officer Husein – Honored as the name of the Dining Hall at AKMIL.
- Cadet Officer Sarsanto – Honored as the name of the Shooting Range at AKMIL.
- Student Soldier Marwoto.
On November 10, 1969, President Soeharto awarded the Kartika Eka Paksi Nararya Star to 27 fallen MA Yogya officers and cadets, including the seven who perished at Plataran.
The commemoration of the 76th anniversary of the Battle of Plataran took place solemnly, with ceremonies, aerial demonstrations, a military jeep exhibition, and a socio-drama reenactment. Today, the name “Plataran” is also preserved as a green urban forest in central Jakarta, forever reminding us of the sacrifices made for Indonesia’s independence.
