forming an estimate of his qualifications as a soldier from personal
observation. I had known him in Mexico when both of us were
lieutenants, and when our service gave no indication that either of us
would ever be equal to the command of a brigade. He stood very high in
the army, however, as an officer and a man. He was brave and
conscientious. His ambition was not great, and he seemed to dread
responsibility. He was willing to do any amount of battling, but always
wanted some one else to direct. He declined the command of the Army of
the Potomac once, if not oftener.

General Alfred H. Terry came into the army as a volunteer without a
military education. His way was won without political influence up to
an important separate command--the expedition against Fort Fisher, in
January, 1865. His success there was most brilliant, and won for him
the rank of brigadier-general in the regular army and of major-general
of volunteers. He is a man who makes friends of those under him by his
consideration of their wants and their dues. As a commander, he won
their confidence by his coolness in action and by his clearness of
perception in taking in the situation under which he was placed at any
given time.

Griffin, Humphreys, and Mackenzie were good corps commanders, but came
into that position so near to the close of the war as not to attract
public attention. All three served as such, in the last campaign of the
armies of the Potomac and the James, which culminated at Appomattox
Court House, on the 9th of April, 1865. The sudden collapse of the
rebellion monopolized attention to the exclusion of almost everything
else. I regarded Mackenzie as the most promising young officer in the
army. Graduating at West Point, as he did, during the second year of
the war, he had won his way up to the command of a corps before its
close. This he did upon his own merit and without influence.

CONCLUSION.

The cause of the great War of the Rebellion against the United Status
will have to be attributed to slavery. For some years before the war
began it was a trite saying among some politicians that "A state half
slave and half free cannot exist." All must become slave or all free,
or the state will go down. I took no part myself in any such view of
the case at the time, but since the war is over, reviewing the whole
question, I have come to the conclusion that the saying is quite true.

Slavery was an institution that requi
