'The question of the six colours taken at Waterloo was discussed at some length a couple of years ago. It is true that French writers, including Houssaye, usually claim six flags captured at Waterloo, but the identity of these is sometimes vague and confusing.
According to Houssaye they were deposited in Caillou Farm and abandoned but one of them (attributed to Fourier Palau – see serial 3 below) was later allegedly handed over to Grouchy's ADC on 26 June 1815 in Soissons but it subsequently disappeared without trace.
French total claims seem to have evolved as follows but I think there is some duplication here.
1. One flag from the Lüneberg battalion.
2. One flag from the 8th battalion KGL.
3. One English flag captured by Fourier Issac Palau from the 9th Cuirassiers in Milhaud's Corps. This was handed over to Grouchy's ADC on 26 June and a receipt written for it – "Recu un drapeau anglais pris ŕ la bataille de Waterloo par le 9e cuirassiers – ce 26 juin 1815 – pour le maréchal, aide de camp, de Lafontaine". The use of the term 'bataille de Waterloo' has been commented on since that was not the name by which the French called the battle.
4. One English flag captured by Marechal de Logis Gauthier of 10th Cuirassiers.
5. One 'Belgian' flag captured by Capitaine Klein de Kleinenberg of the Chasseurs ŕ Cheval, Imperial Guard. Klein's service record says – "eu un cheval tue sous lui dans un carré belge dont il ŕ enleve le drapeau le 18 juin 1815.".
6. One unidentified flag captured by the Chasseurs ŕ Cheval, Imperial Guard
So, there are three identified French units; 9th Cuirassiers, 10th Cuirassiers and the Chasseurs ŕ Cheval. Milhaud's IV Reserve Cavalry Corps, comprising 13th and 14th Cavalry divisions, was initially more or less opposite La Haie Sainte with the Guard light cavalry to its rear. 9th Cuirassiers and 10th Cuirassiers were in Brigade Vial and Brigade de Cruex respectively, of Delort's 14th Division. These units were all certainly in the vicinity of the units that definitely lost colours.
As far as British sources are concerned the losses comprised three colours all taken by cuirassiers.
A. The colour of the Lüneberg Feldbataillon.
B. The King's Colour 8th KGL. Ensign von Moreau who was carrying the King's Colour was wounded and handed it to a sergeant who was killed and the colour taken. The colour was later recovered by Hanoverian cavalry.
C. The King's Colour of 5th KGL. The ensign carrying the King's Colour was killed and the colour taken.
All these came from units of Alten's 3 Division which were also in the vicinity opposite La Haie Sainte on the British centre left. 5th and 8th KGL were in Ompteda's 2nd KGL Brigade, the Lüneberg Feldbataillon was in Kielmansegge';s 1st Hanoverian Brigade. All lost their colours during the fighting around La Haie Sainte in which Milhaud's IV Reserve Cavalry Corps was also involved.
It seems probable that Palau and Gauthier took the colours of 8th and 5th KGL, reported as 'English', which is reasonable enough, though who took which I have not been able to determine. I think, therefore, that the colours in French writing at serial 2 above and those at either serial 3 or 4 might be the same.
The so-called Belgian colour taken by Klein is a bit of a problem as the Dutch-Belgians had no colours so its true identity is a mystery but I think that serials 5 and 6 might also be the same.
If this is right we now have four colours.
1. One flag from the Lüneberg Feldbatallion.
2. One English flag captured by Fourier Issac Palau from the 9th Cuirassiers in Milhaud's Corps. Either 5th or 8th KGL.
3. One English flag captured by Marechal de Logis Gauthier of 10th Cuirassiers. Eother 5th or 8th KGL.
4. One unidentified colour captured by Capitaine Klein de Kleinenberg of the Chasseurs ŕ Cheval, Imperial Guard.'
