One of MacArthur's most controversial acts came in 1932, when the "Bonus Army" of veterans converged on Washington. He sent tents and camp equipment to the demonstrators, along with mobile kitchens, until an outburst in Congress caused the kitchens to be withdrawn. MacArthur was concerned that the demonstration had been taken over by communists and pacifists but the General Staff's intelligence division reported that only three of the march's 26 key leaders were communists. MacArthur went over contingency plans for civil disorder in the capital. Mechanized equipment was brought to Fort Myer, where anti-riot training was conducted.
