Bohemia 4/2/1863 published in its Tagesprogramm almanac of daily social events: ‘Evening in the New Town Theatre: Military Ball of the Royal Cadets and Sergeants’ [k.k. Cadeten und Feldwebel]. No further details were given by this source of the event.

Prager Morgenpost 6/2/1863 published a substantial review, signed with an italicised Greek alpha, of this ‘Kadettenball’. The correspondent wrote: ‘The Cadets’ Ball in the New Town Theatre. The soldiers of the Austrian army have indicated at every opportunity that once the bloody dance of war is played out, they will turn themselves into a fearless and tireless band of [social] dancers. The „Galopp“ goes forward, without a break, through to the „Kehraus“ [the final dance], and only the „Tremblante“ is missing from the dance programme of the gallant comerades. Two days ago these stalwarts assembled for a peacetime festival, a Ball in the generous and particularly appropriate confines of the New Town Theatre. This was suitably festively decorated. The entrance vestibule had been turned into a blossoming, aromatic, living garden. Two dapper sons of Mars collected the invitation cards. We could identify the members of the Ball Committee, through their medals [inscribed] with the bust of Count Clam-Gallas on red ribbons, they were handing out the dance programme, in which, with the exception of the Czardas, no national dance was listed. The dance hall, bathed in a sea of light, was magnificently fitted out and decorated. From the column prominences in the gallery flags fluttered in the colours of Austria-Bavaria and Bohemia, a mighty golden eagle glittered down from the balustrade, on which the ensemble comprising all the military bands of the local garrison gave sound to their cheerful melodies. The rear of the hall was adorned with military trophies formed from weapons, such that they formed a clever and surprising overall picture, the statue of the goddess of war, to both sides the bust of Their Majesties, surrounded by fresh greenery and flowers, which enhanced and beautified the effect of the whole. The entire corps of the officers and cadets of the [Prague] garrison were present in parade uniform; the tunics made a curious contrast to the ball costumes worn by the similarly large number of civilian men present. More than six hundred couples may have danced in the main hall, in addition to which all the portal and gallery boxes were filled with a wreath of blossoming figures of girls and ladies. The Major of the city’s Sharpshooters Corps, Mr Steffek, accompanied by officers of all that Corps, appeared in uniform. At 11 o’clock the strains of the national hymn indicated the arrival of the Commander of the Estates, Count Clam-Gallas, accompanied by His Excellency the Vice-President Governor Baron von Kellersperg, Commander of the Castle FML Baron Melzer, the Generals Baron Dobřensky and Prince Solms, and numerous staff officers. The guests stayed in the hall for more than an hour and talked with many of the ladies and gentlemen. The dancing continued uninterrupted during their visit and afterwards. The cloakroom service seemed to have been entrusted to hands that were not entirely experienced. This splendid occasion will certainly command a central place in the memories of the ladies and gentlemen who took part in it for a long time to come.’

The massed ensembles of the various military corps then present in Prague would have included the 29th Mounted Battalion [Dragoons] and the Prague Civil Sharpshooters Corps.
