Nathan Salisbury died during the Spring (1817) after the year (1816) without summer due to Tambora's eruption in April 1815 in Sumbawa islands, Indonesia. The eruption had global impacts causing loss in agricutlural production and cooler temperatures.
Thousands passed after starvation (no crops) and lack of enough firewood
to stay warm in the 25 degree below zero temperatures in New England as
well as around the world.
Here are the final words about Nathan's death.
This account focuses almost solely on conditions in the Northeastern United States and parts of eastern Canada. The Year 1816 was also unusually cold elsewhere. Reports from northern Europe indicate similar impacts on crops and the population, just as the continent was emerging from the chaos of the Napoleonic Wars. The unusual weather lead to riots in France shaking the new constitutional monarchy of Louis XVIII and Tallyrand. Some historians believe the famine begun in 1816 created conducive conditions for the typhus epidemic that killed millions from 1817-1819. It is suspected that Nathan died from typhus.
