Rivers often act as really effective and accessible trade routes, so the historian could use this map to analyse trade routes between Early River Valley Civilizations.
Hope this helps :))
On the morning of January 30, 1968 just as people were preparing for the lunar new year, 13 cities in Central South Vietnam were attacked by the Viet Cong forces. Twenty four hours later, cities, towns, government buildings, U.S. and Army of the Republic of Vietnam (ARVN) military bases throughout South Vietnam were also hit in a total of over 120 attacks. In Saigon, a platoon of Viet Congs were able to enter the U.S. embassy's courtyard before it was crushed. The Viet Cong forces were daring and the attacks were well planned and it also showed that the Viet Congs could not be trusted. For several years during the Vietnam war, there was always an informal truce between North Vietnam and South Vietnam during the lunar new year, Tet being the most important date in the Vietnamese calendar.
