Panorama of the Battle of Waterloo by Ionic pilasters, and crowned with parapet with a frieze of palmettes. The entrance porch has two pairs of Tuscan columns supporting a triangular pediment. The rotunda houses an oil-on-canvas painting completed by French artist Louis Dumoulin in 1912, with 14 canvas panels sewn together to create a cylinder approximately in circumference and high. It is lit from above by a ring of glazing around the edge of the conical roof and is viewed from a high platform at the centre of the rotunda. The painting depicts several different episodes from the Battle of Waterloo in 1815, concentrating on charges
Battle of Waterloo commanders took place near "La Belle Alliance", with this occurring at around 21:00. Waterloo cost Wellington around 15,000 dead or wounded and Blücher some 7,000 (810 of which were suffered by just one unit: the 18th Regiment, which served in Bülow's 15th Brigade, had fought at both Frichermont and Plancenoit, and won 33 Iron Crosses). Napoleon's losses were 24,000 to 26,000 killed or wounded and included 6,000 to 7,000 captured with an additional 15,000 deserting subsequent to the battle and over the following days. At 10:30 on 19 June General Grouchy, still following his orders, defeated General Thielemann at Wavre
