Initially, George Washington was reluctant to inoculate his troops. But as he watched many of his men fall victim to smallpox, Washington believed that he would be able to keep his troops healthy through sanitary and quarantine methods. There were several events that contributed to the change of Washington's policy. First, Washington recognized that quarantine and attempted cleanliness were not enough to keep his vital troops healthy and in fighting form. Additionally, many prominent members of colonial society were having themselves and their families inoculated. Eventually, even George Washington's wife, Martha Washington was herself inoculated. It was not long after this that Washington initiated the inoculation of the American troops. Washington recognized the dangers of inoculating these men; many patients died as result of the infection caused by inoculation. However, the importance of keeping his men healthy outweighed the risks, and almost all Continental soldiers were inoculated against smallpox. Washington (a survivor of smallpox himself) understood the danger that smallpox posed to his men, saying "Necessity not only authorizes but seems to require the measure, for should the disorder infect the Army . . . we should have more to dread from it, than from the Sword of the Enemy." However, it was more complex than just Washington making this decision. Local officials were concerned that the inoculation of soldiers would lead to the accidental spread of smallpox among civilians. But Washington persisted in his quest and managed to get the majority of his soldiers inoculated. Along with the rise in popularity of the practice, Washington's decision to inoculate his troops was also extremely strategic; he was able to realize the deep impact an epidemic would have on his troops. Immunity was initially more widespread among the British men than the Americans. This was due to the more accepted practice of inoculation in Europe and the high rate of childhood cases, resulting in immunity. With this, an epidemic spread among Americans could prove disastrous to the American cause. With his men at Valley Forge inoculated, Washington was able to proceed with more confidence, knowing that at least his men would not be struck down by the smallpox virus.
