ion 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 required unusual guarantees for its
security wherever it existed; and in a country like ours where the
larger portion of it was free territory inhabited by an intelligent and
well-to-do population, the people would naturally have but little
sympathy with demands upon them for its protection. Hence the people of
the South were dependent upon keeping control of the general government
to secure the perpetuation of their favorite institution. They were
enabled to maintain this control long after the States where slavery
existed had ceased to have the controlling power, through the assistance
they received from odd men here and there throughout the Northern
States. They saw their power waning, and this led them to encroach upon
the prerogatives and independence of the Northern States by enacting
such laws as the Fugitive Slave Law. By this law every Northern man
was obliged, when properly summoned, to turn out and help apprehend
the runaway slave of a Southern man. Northern marshals became
slave-catchers, and Northern courts had to contribute to the support
and protection of the institution.

This was a degradation which the North would not permit any longer
