The fortress of Makawanpur has a historical and military significance for the Nepalese. It was here that the Nepalese defeated superior forces of Mir Qasim in 1763 and seized 500 guns and two cannons. Later on, these weapons were used by Nepalese troops and four companies were established regular, namely, Srinath, Kalibox, Barda Bahadur (Bardabahini) and Sabuj. (Purano) Gorakh Company was established a few months later. It was the first rank and file system beginning a proper organizational history for the Royal Nepalese Army. The battle against Mir Qasim troops was the first battle of the Royal Nepalese Army against a foreign power.
