The attack began at 4:44 am, when the mine exploded, leaving a 200 foot long, 50-60 foot wide crater in the line, some 25 to 30 feet deep in places. A division under General Ledlie led the attack, and marched straight into the hole in the line. They were to continue on towards Cemetery Hill, but were bogged down within the crater. Two other divisions followed them in, to occupy the grounds on both flanks of Ledlie, while he continued forward.
