I have recently found a May 15th 1863 letter written by Private James D. Stearns. The sharpshooters were posted in Suffolk, Virginia. Here is is small clip of the military news he reported:
"It appeared that the 165th and 166th Pennsylvania conscript regiments were sent out as scouts & then coming near each other in the flanking position, they supposed each other Rebs & fired into each other and each run or fell back with the loss of 3 killed and 5 wounded. There is not much dependence to be put on the conscript regiments."
