He was speaking in general to stop fighting and shedding each others blood! Hope this helps

Explanation:

In November of 1863 President Abraham Lincoln was invited to attend the dedication of the Soldiers' National Cemetery at Gettysburg, Pennsylvania. Seventeen acres adjacent to the town's regular cemetery had been purchased for the burial of the soldiers killed in the Battle of Gettysburg. The chief orator was to be the eloquent Edward Everett of Massachusetts. Mr. Lincoln would then add a few appropriate remarks in honor of the dead. Everett ended up speaking for about two hours; Lincoln spoke for less than three minutes.

While in Gettysburg, where would the president stay? David Wills, a Gettysburg attorney, was the chairman of the cemetery board. His home fronted on the public square. Wills invited the president to stay overnight at his home.

The president rode to Gettysburg on a special train of four cars furnished by the Baltimore and Ohio Railroad. The train left Washington, D.C. and traveled through Maryland to Baltimore. There it was transferred to the North Central tracks and proceeded on that line to Hanover Junction, Pennsylvania. There it changed to the Hanover Line for the remainder of the trip to Gettysburg.

Lincoln arrived in Gettysburg at 5:00 P.M. on November 18. He ate dinner and spent the night at Wills' mansion before giving his famous address the next day.

the answer is a) to be able to obey them.
