I am confused by the statement

On April 19, 1865, during a minor combat action near Newton, North Carolina, the battery was forced to surrender after being overrun following the collapse of the Confederate infantry to whom they were in support.

It appears that the 10th Michigan paroled a number of prisioners at Newton, North Carolina on April 19, 1865, but these seem to have been reminants from Lee's Army.
