About six o’clock in the morning he stood before the royal castle on the Place de Meix, where the Prince-Admiral had fixed his quarters, King Leopold having offered him the castle to reside in.

In spite of the early hour Heideck was at once conducted to the Prince’s study.

“Your Royal Highness,” said Heideck, “I have a report of the utmost importance to make. These orders of the English Admiralty have fallen into my hands.”

The Prince motioned him to a seat by his desk. “Be good enough to read the orders to me, Herr major.”

Heideck read the important document, which ran as follows:—

“The Lords of the Admiralty think it desirable to attack the German fleet first, as being the weaker. This attack must be carried out before the Russian fleet is in a position to go to its assistance in Kiel harbour. Therefore a simultaneous attack should be made on the two positions of the German fleet on the 15th of July.”

“On the 15th of July?” repeated the Prince, who had risen in great excitement. “And it is the 11th to-day! How did you get possession of these orders, Herr major? What proof have you that this document is genuine?”

“I have the most convincing reasons for believing it genuine, your Royal Highness. You can see for yourself that the orders are written on the blue stamped paper of the English Admiralty.”

“Very well, Herr major! But that would not exclude the idea of a forgery. How did you come into possession of this paper?”

“Your Royal Highness will excuse my entering into an explanation.”
