Ominously, in 1919, the Third Anglo-Afghan War began in the wake of Amir Habibullah's assassination and institution of Amanullah in a system blatantly influenced by the Kabul mission. In addition, in India, Gandhi's call for protest against the Rowlatt Act achieved an unprecedented response of furious unrest and protests. The situation, especially in Punjab, was deteriorating rapidly, with disruptions of rail, telegraph and communication systems. The movement was at its peak before the end of the first week of April, with some recording that "practically the whole of Lahore was on the streets, the immense crowd that passed through Anarkali was estimated to be around 20,000." In Amritsar, over 5,000 people gathered at Jallianwala Bagh. This situation deteriorated perceptibly over the next few days. Michael O'Dwyer is said to have been of the firm belief that these were the early and ill-concealed signs of a conspiracy for a coordinated uprising around May, on the lines of the 1857 revolt, at a time when the British would have withdrawn to the hills for the summer. The Amritsar massacre, as well as responses before and after it, was the end result of a concerted plan of response from the Punjab administration to suppress such a conspiracy. James Houssemayne Du Boulay is said to have ascribed a direct relationship between the fear of a Ghadarite uprising in the midst of an increasingly tense situation in Punjab, and the British response that ended in the massacre.
