According to the US Census the number of slaves reported as fugitives in free states in 1850 was 1,011. That number represented 1 in 3,165 slaves. The annual loss to slaveholders had increased over the years which was exacerbated by the north’s reluctance to return runaways. The Fugitive Slave Act of 1850 replaced the weakened fugitive Slave Act of 1793 which faced increased resistance from northern states. The new act added provisions for harsher punishment and fines for those who interfered in the capture of a runaway slave as well as gave incentives to those who captured escapees.

That's an interpretive question that would ask us to get inside the mind of Lincoln from a distance a century and a half away. We do know that Lincoln long had moral and political objections to slavery. He had outlined some of those thoughts in a speech given in Peoria, Illinois, in 1854. But Lincoln's views on what to do about slavery were something that took shape over time. In the Peoria speech, he suggested that perhaps slaves should be freed in order to be returned to Africa. But as the conflict over slavery grew and the Civil War became a reality, Lincoln became firmer in seeing this as a struggle not just over preserving the Union but also a battle for human dignity and the principle of equality. And so in the Gettysburg Address, in 1863, he affirmed the principle stated by the Declaration of Independence, that all men are created equal. The massive number of casualties at the Battle of Gettysburg certainly gave impetus to Lincoln's words about preserving the Union and government of the people, by the people and for the people. But those ideas had been central to Lincoln's worldview before Gettysburg as well as in that speech.
