Head Quarters, Army of the Potomac Camp near Harrison's Landing, Va. July 7th 1862
You have been fully informed, that the Rebel army is in our front, with the purpose of overwhelming us by attacking our positions or reducing us by blocking our river communications. I can not but regard our condition as critical and I earnestly desire, in view of possible contingencies, to lay before your Excellency, for your private consideration, my general views concerning the state of the rebellion; although they do not strictly relate to the situation of this Army or strictly come within the scope of my official duties. These views amount to convictions and are deeply impressed upon my mind and heart.
Our cause must never be abandoned; it is the cause of free institutions and self government. The Constitution and the Union must be preserved, whatever may be the cost in time, treasure and blood. If secession is successful, other dissolutions are clearly to be seen in the future. Let neither military disaster, political faction or foreign war shake your settled purpose to enforce the equal operation of the laws of the United States upon the people of every state.
The time has come when the Government must determine upon a civil and military policy, covering the whole ground of our national trouble. The responsibility of determining, declaring and supporting such civil and military policy and of directing the whole course of national affairs in regard to the rebellion, must now be assumed and exercised by you or our cause will be lost. The Constitution gives you power sufficient even for the present terrible exigency.
This rebellion has assumed the character of a War: as such it should be regarded; and it should be conducted upon the highest principles known to Christian Civilization. It should not be a War looking to the subjugation of the people of any state, in any event. It should not be, at all, a War upon population; but against armed forces and political organizations. Neither confiscation of property, political executions of persons, territorial organization of states or forcible abolition of slavery should be contemplated for a moment. In prosecuting the War, all private property and unarmed persons should be strictly protected; subject only to the necessities of military operations. All private property taken for military use should be paid for or receipted for; pillage and waste should be treated as high crimes; all unnecessary trespass sternly prohibited; and offensive demeanor by the military towards citizens promptly rebuked. Military arrests should not be tolerated, except in places where active hostilities exist; and oaths not required by enactments -- Constitutionally made -- should be neither demanded nor received. Military government should be confined to the preservation of public order and the protection of political rights.
Military power should not be allowed to interfere with the relations of servitude, either by supporting or impairing the authority of the master; except for repressing disorder as in other cases. Slaves contraband under the Act of Congress, seeking military protection, should receive it. The right of the Government to appropriate permanently to its own service claims to slave labor should be asserted and the right of the owner to compensation therefore should be recognized. This principle might be extended upon grounds of military necessity and security to all the slaves within a particular state; thus working manumission in such [a] state -- and in Missouri, perhaps in Western Virginia also and possibly even in Maryland the expediency of such a military measure is only a question of time. A system of policy thus constitutional and conservative, and pervaded by the influences of Christianity and freedom, would receive the support of almost all truly loyal men, would deeply impress the rebel masses and all foreign nations, and it might be humbly hoped that it would commend itself to the favor of the Almighty. Unless the principles governing the further conduct of our struggle shall be made known and approved, the effort to obtain requisite forces will be almost hopeless. A declaration of radical views, especially upon slavery, will rapidly disintegrate our present Armies.
The policy of the Government must be supported by concentrations of military power. The national forces should not be dispersed in expeditions, posts of occupation and numerous Armies; but should be mainly collected into masses and brought to bear upon the Armies of the Confederate States; those Armies thoroughly defeated, the political structure which they support would soon cease to exist.
In carrying out any system of policy which you may form, you will require a Commander in Chief of the Army; one who possesses your confidence, understands your views and who is competent to execute your orders by directing the military forces of the Nation to the accomplishment of the objects by you proposed. I do not ask that place for myself. I am willing to serve you in such position as you may assign me and I will do so as faithfully as ever subordinate served superior.
I may be on the brink of eternity and as I hope forgiveness from my maker I have written this letter with sincerity towards you and from love of my country.
Very respectfully your obdt svt
