 very great. The Karlštýn castle had been built by Charles IV as a refuge for the royal family in time of war, and also as a stronghold where the Bohemian crown and other royal jewels could be safely deposited. Some writers have therefore conjectured that Korybutovič believed that the Bohemian crown jewels were still in the Karlštýn castle, and that he wished to obtain possession of them. This is exceedingly improbable. Korybutovič’s Bohemian advisers certainly well knew how great an importance the Bohemians, like the Hungarians, attach to the possession of the royal insignia and to the coronation of their kings, but they must have known equally well that King Sigismund had immediately after his coronation in 1420 caused the crown of Bohemia and the other crown jewels to be sent to Moravia and afterwards to Hungary. The siege of the Karlštýn is, at any rate, the principal military event connected with the first short stay of Korybutovič in Bohemia. It is here to be particularly regretted that we have but few and short contemporary accounts of the siege, and these have rather the character of romance than of history. The attempts of modern writers to reconstruct the siege have been but moderately successful. It is probable that Korybutovič’s Bohemian and Polish soldiers began a regular siege of the Karlštýn on May 20, but Korybutovič himself only took over the command of the besieging army on June 4. The castle of Karlštýn, built by the Emperor Charles IV, King of Bohemia, about the year 1350, had a position which could not be considered strong, even if we consider the very primitive condition of artillery at the beginning of the fifteenth century, being situated on an isolated hillock surrounded somewhat closely by higher hills. General Kohler in his interesting work, which I have already quoted, expresses surprise that Charles IV, who had been present at the battle of Crécy, where fire-arms had been used, should yet, when building the Karlštýn a few years later, not have taken the use of artillery into account. It is certain that men began only very gradually
