The answer is:. E. Grant put the Confederates under siege.

Explanation:

There were a series of battles around St Petesburg. Ulysses S. Grant's Army and Robert E. Lee's Army of Northern Virginia collided as the Union troops attacked Petersburg.

In June 1864, in a brilliant tactical maneuver, Grant marched his army around the Army of Northern Virginia, crossed the James River unopposed, and advanced his forces to Petersburg. On June 15, the first day of the Battle of Petersburg, some 10,000 Union troops moved against the Confederate defenders of Petersburg, made up of only a few thousand armed old men and boys. Grant's army dug trenches and began a prolonged siege of Petersburg.
