massacre According to Indonesian accounts, on 14 October, Kido's men disarmed Indonesian guards of a water reservoir. Later that day, an Indonesian doctor named Kariadi was shot and killed while he was heading to the reservoir to check the water for any poison. Near the location, over 300 Japanese civilians who had been relocated from Kendal were temporarily stationed at Boeloe prison. The Indonesian Special Police tried to lead the group away around 10:30 PM that day, but the group offered resistance with melee weapons and some small arms smuggled in by Kido's men. The group was slaughtered, with only a handful managing to escape. Fighting Prior to learning about the massacre, Kido ordered his men to launch an offensive against Indonesian forces at around 2 a.m. on 15 October, though gunshots had been heard in the city the night before. In another account, Kido only ordered an offensive after Indonesians burned an ammunition depot at around 3 a.m. For the ordered offensive, Kido divided his forces into two groups, comprising 383 and 94 men respectively. By 3 p.m. that day, Kido had mobilized all Japanese around the area under his command. The BKR sent reinforcements to the city from various locations across Central Java. Japanese forces captured the Bulu prison around 4:30 p.m. on 16 October and discovered the remnants of the slaughter. Afterwards, accounts noted that Kido's men began "fighting mad", taking no prisoners and conducting large-scale executions of captives. Some accounts also noted that the executions had started prior to the capture of the prison. On 19 October, soldiers from the British 10th Gurkha Rifles landed in Semarang. After a brief shootout with the Japanese forces who mistook them for Indonesian reinforcements (killing two Gurkhas and four Japanese), Japanese soldiers handed control of the city to the Gurkhas. Japanese soldiers proceeded to assist Allied forces in Magelang and Ambarawa afterwards. Aftermath Japanese historian Kenʼichi Gotō wrote that around two thousand Indonesians in Semarang were killed due to the incident, while on the other hand Dutch historian P. M. H. Groen suggested that less than 300 were killed. Eyewitness accounts suggested that some streets in Semarang were "littered with corpses" and in one locale a ditch was blocked by corpses. Japanese historian Kenʼichi Gotō wrote that 187 were killed in fighting, while Kido reported forty-two soldiers killed, forty-three wounded and 213 missing, not including those massacred at Bulu
