What is the mutiny of the second Maine?

Answer 1

As I recall, the 2nd Maine Regiment had suffered many casualties, so the decision was made to absorb them into the 20th Maine Regiment. The men of the 2nd Maine felt betrayed because they had only signed up to fight for 1 year and now they were being asked to serve longer and with another group of men. So, they threatened to refuse to fight.

This may not be totally accurate as some of this comes from the movie "Gettysburg", as the 20th Maine was the regiment lead by Col. Chamberlain and gallantly defended Little Round Top.

Google those facts and see if it is accurate.

I was correct!

By the summer of 1863, Chamberlain had been promoted to colonel and marched the 20th Maine northward in pursuit of Lee. On July 1, the Fifth Corps marched to Hanover, Pennsylvania before turning west toward Gettysburg. An overnight forced march got the troops to a location in rear of Cemetery Ridge the next day and Chamberlain's men took a brief but grateful rest. It was here that Chamberlain faced the distasteful duty of addressing "mutinous" soldiers assigned to the 20th Infantry from the old 2nd Maine, which had been mustered out. A group of men whose enlistments had not expired refused to carry arms and were placed under arrest. Chamberlain's brief speech and his pledge to plead their case caused all but a handful to take arms and join the ranks of the 20th for the coming battle.
