[1][2][3][4] In March 1921, during the early stages of the Mongolian Revolution of 1921, a Mongolian guerrilla army led by Damdin Sükhbaatar as Supreme Commander launched an offensive at the Chinese garrison at Kyakhta Maimaicheng (Altanbulag, Selenge).

The offensive followed a failed attempt by the Mongolian People's Party central committee to reach an ultimatum with Chinese troops.

Despite Sükhbaatar's 400-man army being heavily outnumbered by the Chinese, he led his troops to victory in taking the town.

The Chief of General Staff usually takes part in a wreath laying ceremony on Sükhbaatar Square.
