Biographer James G. Randall dissected Lincoln's successful techniques:[195]

his restraint, his avoidance of any outward expression of truculence, his early softening of State Department's attitude toward Britain, his deference toward Seward and Sumner, his withholding of his paper prepared for the occasion, his readiness to arbitrate, his golden silence in addressing Congress, his shrewdness in recognizing that war must be averted, and his clear perception that a point could be clinched for America's true position at the same time that satisfaction was given to a friendly country.
Lincoln painstakingly monitored the telegraph reports coming into the War Department. He tracked all phases of the effort, consulting with governors, and selecting generals based on their success, their state, and their party. In January 1862, after complaints of inefficiency and profiteering in the War Department, Lincoln replaced War Secretary Simon Cameron with Edwin Stanton. Stanton centralized the War Department's activities, auditing and canceling contracts, saving the federal government $17,000,000.[196] Stanton was a staunch Unionist, pro-business, conservative Democrat who gravitated toward the Radical Republican faction. He worked more often and more closely with Lincoln than any other senior official. "Stanton and Lincoln virtually conducted the war together", say Thomas and Hyman.
