Washington, July 18, 1864.

To Whom it may concern:

Any proposition which embraces the restoration of peace, the integrity of the whole Union, and the abandonment of slavery, and which comes by and with an authority that can control the armies now at war against the United States will be received and considered by the Executive government of the United States, and will be met by liberal terms on other substantial and collateral points; and the bearer, or bearers thereof shall have safe-conduct both ways.

Abraham Lincoln
