twelve o'clock
For an hour the battalion marched without stopping . The orders `` shoulder arms , '' `` support arms , '' `` right shoulder shift '' relieved them occasionally ; but some legs began to ache before a halt was permitted . During the next hour they marched most of the way with the `` route step . '' At twelve o'clock they halted for dinner and an hour 's rest . The haversacks of the soldiers had been filled with crackers and cold ham , and they had a jolly dinner in a grove where they stopped . About four o'clock in the afternoon , they reached the upper end of the lake , and the orders necessary for forming a camp were given . The tents were pitched , the boundaries of the camp marked out , and a detail for guard duty was made from each company .
