Does "mark the degenerate counsels " mean "point out the bad counsels?"
Context:
And now we find them, in further contempt of the modes of honorable warfare, supplying the place of a conquering force by attempts to disorganize our political society, to dismember our confederated Republic. Happily, like others, these will recoil on the authors; but they
mark the degenerate counsels from which they emanate, and if they did not belong to a sense of unexampled inconsistencies might excite the greater wonder as proceeding from a Government which founded the very war in which it has been so long engaged on a charge against the disorganizing and insurrectional policy of its adversary.
