1860s, Letter to Horace Greeley (1862)
“VIII. On the face of this wide earth, Mr. President, there is not one disinterested, determined, intelligent champion of the Union cause who does not feel that all attempts to put down the Rebellion and at the same time uphold its inciting cause are preposterous and futile--that the Rebellion, if crushed out tomorrow, would be renewed within a year if Slavery were left in full vigor--that Army officers who remain to this day devoted to Slavery can at best be but half-way loyal to the Union--and that every hour of deference to Slavery is an hour of added and deepened peril to the Union, I appeal to the testimony of your Ambassadors in Europe. It is freely at your service, not at mine. Ask them to tell you candidly whether the seeming subserviency of your policy to the slaveholding, slavery-upholding interest, is not the perplexity, the despair of statesmen of all parties, and be admonished by the general answer.”

Context: The cause of the great War of the Rebellion against the United States 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.

Context: These semi-traitors [Union generals who were not hostile to slavery] must be watched. — Let us be careful who become army leaders in the reorganized army at the end of this Rebellion. The man who thinks that the perpetuity of slavery is essential to the existence of the Union, is unfit to be trusted. The deadliest enemy the Union has is slavery — in fact, its only enemy.
