Days later, the Preparatory Committee for Indonesian Independence (PPKI) announced the establishment of the People's Security Body (BKR).

Under this agreement, the Indonesian government was forced to recognize territories that had been taken under Dutch Control including West Java.

[7] During the same year, Amir Machmud joined his troops in a crackdown on the Communist Party of Indonesia (PKI) at Madiun.

[citation needed] In 1949, with the Dutch beginning to withdraw from Indonesia, Amir Machmud and his troops returned to West Java.

In 1950, Amir Machmud was also involved in a crackdown against the "Just Ruler" Legion (APRA), a military group that entered Bandung and started targeting TNI soldiers.

[citation needed] After the end of the War of Independence, the military was reorganized into seven "Territories and Armies" (Teritorium dan Tentara).

The day would finish with Suharto taking back control of the situation in Jakarta and the PKI being accused of being behind the coup attempt.

[13][14] In December 1965, Amir Machmud was appointed Commander of KODAM V/Jaya and he was now responsible for the security of Jakarta and its surrounding areas.

[citation needed] At the beginning of 1966, Sukarno's popularity declined enough for people to openly oppose him via the means of protests.

Ten minutes into the meeting, Amir Machmud was approached by Brigadier General Sabur, the Commander of the Presidential Bodyguards.

According to Amir Machmud, Suharto asked the three generals to tell Sukarno of his readiness to restore security should the President order it.

Sukarno then began discussing options with Basuki, Jusuf, and Amir Machmud before finally asking them how he could take care of the situation.

On the way back to Jakarta, Amir Machmud asked to read the document and seemed shocked to find out that it was a handover of power to Suharto.

Sukarno was angry that Suharto had banned the Communist Party of Indonesia (PKI) and told the three generals that Supersemar did not contain such instructions.

Sukarno then ordered that a letter be produced to clarify the contents of Supersemar but nothing ever came up apart from the copies that former Ambassador to Cuba, AM Hanafi recollected.

[citation needed] As Suharto removed Sukarno from power and replaced him as president in 1967, Amir Machmud continued as Commander of Kodam V/Jaya.

[1][11][18] During his tenure as Minister of Home Affairs, Amir Machmud developed a reputation of being tough on government opponents and dissidents.

In 1969, he banned civil servants from being involved in politics but would encourage them to vote to Golkar in Legislative Elections as a sign of loyalty to the government.

[citation needed] In addition to being Minister of Home Affairs, Amir Machmud was also the Chairman of the General Elections Institution (LPU).
