when did the monk set himself on fire
Thích Quảng Đức Thích Quảng Đức (Vietnamese: [tʰǐc kʷâːŋ ɗɨ̌k] ( listen); 1897—11 June 1963, born Lâm Văn Túc), was a Vietnamese Mahayana Buddhist monk who burned himself to death at a busy Saigon road intersection on 11 June 1963.[1] Quảng Đức was protesting the persecution of Buddhists by the South Vietnamese government led by Ngô Đình Diệm. Photographs of his self-immolation were circulated widely across the world and brought attention to the policies of the Diệm government. John F. Kennedy said in reference to a photograph of Đức on fire, "No news picture in history has generated so much emotion around the world as that one."[2] Malcolm Browne won a Pulitzer Prize for his photograph of the monk's death.[3][4]
History of gunpowder At this point the formula contained too little saltpeter (about 50%) to be explosive, but the mixture was highly flammable, and contemporary weapons reflected this in their deployment as mainly shock and incendiary weapons. One of the first, if not the first of these weapons was the fire arrow.[13] The first possible reference to the use of fire arrows was by the Southern Wu in 904 during the siege of Yuzhang, when an officer under Yang Xingmi by the name of Zheng Fan (鄭璠) ordered his troops to "shoot off a machine to let fire and burn the Longsha Gate," after which he and his troops dashed over the fire into the city and captured it, and he was promoted to Prime Minister Inspectorate for his efforts and the burns his body endured.[14] A later account of this event corroborated with the report and explained that "by let fire (飛火) is meant things like firebombs and fire arrows."[13] Arrows carrying gunpowder was possibly the most applicable form of gunpowder weaponry at the time, as early gunpowder may have only produced an effective flame when exposed to oxygen, thus the rush of air around the arrow in flight would have provided a suitable catalyst for the reaction.[13]
