Actually Maryland's abolition of slavery was included in the state constitution drafted in April 1864 and ratified that November. Incidentally, Maryland soldiers voting in that ratification referendum were 10 to 1 in favor of abolition.
Close enough to the point. They certainly didn't abolish it around April 12, 1861.

I daresay it would have been an uncomfortable situation for a soldier to have any other opinion at this time. It's a wonder that it was only 10 to 1.
