Official Reports Chancellorsville
The War of the Rebellion Official Records Volume 25 part 1.
After a vaccine that was intended to inoculate the regiment against smallpox actually gave several of the men the disease, the 20th Maine was ordered into quarantine.
Neither Lieutenant Colonel Chamberlain nor Colonel Ames were very pleased to be stuck in quarantine with a sick regiment while
a battle was going on. Ames managed to make his escape leaving Chamberlain in command of the regiment. After pleading at headquarters to be allowed to
take the regiment in, Chamberlain was finally able to get assigned the duty of guarding the telegraph line.
On page 5 of Gubernatorial Race Clippings
we see that Chamberlain begged to take the regiment in, "if they could do nothing else they would give the rebels the small-pox"
- For General Meade's report commending Ames for his actions as "volunteer aide-de-camp" see page 509.
