[2] Boworadej moved back to Siam in 1900 to serve in Royal Thai Army's Command and General Staff Department.

[7] The Special Court's "Decision on the Insurrection" noted that Prince Boworadej had once consulted General Phahon and Phaya Srisith about the plan to change the government.

At the end of July 1933, Phibun and Supha sent a circular to a number of prominent individuals warning them to "exercise peace of mind", otherwise the "party will be forced to bring stringent measures to bear on you."

A number of members of the royal house received the letter, including Prince Boworadej, who was in Hua Hin with the king at that time.

[10] In 1933, Prince Boworadej plotted with Colonel Phraya Sri Sitthi Songkhram (Thai: พระยาศรีสิทธิ์สงคราม), the commander of the military in Bangkok, to stage a coup d'état to unseat the Phahon government and replace it with a more traditional one.

In reply, the besiegers dropped leaflets on the city from airplanes, accusing the people's party of restraining King Prajadhipok.

[15] Faced with the prospect of a full-scale battle to remove the existing leadership, Boworadej adopted a more conciliatory approach by entering into negotiations in which he called on the government to allow the king a greater political role.

The government broadcast a radio appeal to rebel troops to surrender and offered a ten thousand baht reward for the capture of Boworadej.
