Butler's failed attempt to take Petersburg.Charles Francis Adams, who, as a cavalry officer, served in Butler's campaign, compares Grant's maneuvers of 1864 to Napoleon's of 1815. While Napoleon advanced upon Wellington it was essential that Grouchy should detain Blucher. So Butler was to eliminate Beauregard while Grant struck at Lee. With forty thousand men, he was ordered to land at Bermuda Hundred, seize and hold City Point as a future army base, and advance upon Richmond by way of Petersburg, while Grant meanwhile engaged Lee farther north. Arriving at Broadway Landing, seen in the lower picture, Butler put his army over the Appomattox on pontoons, occupied City Point, May 4th, and advanced within three miles of Petersburg, May 9th. The city might have been easily taken by a vigorous move, but Butler delayed until Beauregard arrived with a hastily gathered army and decisively defeated the Federals at Drewry's Bluff, May 10th. Like Grouchy, Butler failed.
