A specially formed tunnelling company had burrowed 65 metres to a position beneath a German strongpoint and planned nearly two tonnes of Ammonal, the most powerful explosive of the time. The crater was immediately rushed and occupied by the British infantry. Today the crater is a small lake just in front of the hotel.
