"Just after writing those we were called up to defend a new position on the left, where the terrible storming of the bridge over the Antietam took place"

This quote is from Joshua Chamberlain, a Union officer in the American Civil War. He is explaining a battle that occurred at the Battle of Antietam. The quote recommends that he and his soldiers had actually simply finished composing something when they were called up to defend a new position left wing. This position was most likely the bridge over the Antietam Creek, which was the site of a strong fight. The bridge was a strategic point for the Union forces, and the Confederate forces tried to take it several times. The fight was extreme and bloody, with both sides suffering heavy casualties. Chamberlain's quote suggests that he and his troops were contacted to defend the bridge and were most likely involved in the fighting. The quote also recommends that the battle was a difficult one, as it was referred to as a "dreadful storming".
