Hatta and Sukarno that the PPKI would be formed on 18 August and that Indonesia would be independent with Japanese supervision. Japanese surrender Hatta and Sukarno returned to Indonesia on 14 August. In Hatta's case, Syahrir was waiting for him with news of the atomic bombs in Hiroshima and Nagasaki. Syahrir told Hatta that they would have to encourage Sukarno to proclaim Indonesia's independence immediately, because in a couple of days the Japanese might not be there to provide supervision. Syahrir told Hatta not to worry about the Japanese authorities because the people would be on their side. Syahrir and Hatta then went to see Sukarno, with Syahrir repeating his argument in front of Sukarno. Hatta then spoke out, saying that he was worried the Allies would see them as Japanese collaborators. Sukarno shared this sentiment and Syahrir left the meeting out of frustration. The next day, on 15 August 1945, Japan surrendered to the Allies. In Indonesia, the news was only a rumor and had not been confirmed. Hatta and Sukarno went to the office of the Japanese Occupational Government in Jakarta, only to find it empty. Hatta and Sukarno then went to Maeda who confirmed that Japan had surrendered to the Allies. Hatta and Sukarno seemed shocked that Japan had surrendered. During the afternoon, Hatta and Sukarno were confronted by Indonesian youths who wanted independence to be proclaimed as soon as possible. A heated exchange followed, with Sukarno telling the youths to have more patience. Hatta, who was aware of this and Sukarno's superiority in the exchange, sarcastically commented on the youths' inability to proclaim independence without Sukarno. Kidnapping and proclamation On the morning of 16 August 1945, Indonesian youths kidnapped both Hatta and Sukarno and took them to the town of Rengasdengklok where they continued trying to force Hatta and Sukarno to declare independence, but without success. In Jakarta, there was panic as the PPKI was due to start meeting that day and had planned to elect Sukarno as chairman and Hatta as vice-chairman. When knowledge of Hatta and Sukarno's whereabouts became available and the Japanese surrender was confirmed, Achmad Subardjo, a PPKI representative, went to Rengasdengklok to break the news to Hatta and Sukarno. That night, Hatta and Sukarno returned to Jakarta where, at Maeda's house, they worked on the Proclamation of Independence. Finally, on 17 August 1945, at Sukarno's residence, Indonesia's Independence was finally proclaimed
