despite the highest protection by august prince of prussia, burg nearly had not been promoted to the rank of a captain. in this promotion drama, burg initially had to compromise to be promoted to the rank of a "captain of the army" only, a rank that was not equivalent to a captain of the artillery. then he was invited to be baptized, to make the promotion possible, what burg ultimately rejected. burg requested the baptism once in 1824, but then he postponed his request "because of family relationships" on 16 november 1824.
