"Flag to Rebound. Lieutenant Peter Corbold to report on board as soon as convenient."

Peter was given the message. He guessed what was "in the wind" and hastened to obey. "As soon as convenient" meant, he knew, in naval parlance "as sharp as you jolly well can, and the quicker the better". Rigged out in a white drill tropical uniform lent by a brother officer who luckily had lost only a small amount of kit during the action, Peter went over the side into the waiting picket-boat and was soon on his way to the Flagship.

"I have selected you, Mr. Corbold," said the Admiral in his usual style of coming straight to the point, "to be the bearer of this letter to the President of Rioguay, since, I believe, you speak the language and have been a resident in Rioguay, You will wait till noon for a reply. The ultimatum is unsealed. Read it, and make yourself acquainted with the terms."

Peter did so. The British ultimatum was brief and emphatic. It demanded the unconditional surrender of San Antonio, with all warships, forts, military, naval, and aircraft stores and equipment. No hostages were demanded, and a promise was given that private and civil property would be strictly respected. The question of indemnities with respect to the wanton destruction of British mercantile shipping would be impartially dealt with at a later date. Failing an acceptance of the terms by noon, the port and fortified positions of San Antonio would be bombarded at 3 p.m.

The ultimatum was then sealed and again handed to Peter for delivery.

Five minutes later, the envoy was in the stern-sheets of the picket-boat on his way to San Antonio. He was unarmed, as were the crew. From the jack-staff in the bows was displayed a large white flag.

It was a good half-hour's run to the naval port landing-steps. The picket-boat was not fired upon, although Peter would not have been surprised if the Rioguayan forts and ships had done so. As he passed the shell-shattered warships lying at anchor off the town, their crews regarded the British boat with unfeigned interest, but without any demonstration of anger. The wharves, too, were crowded with spectators, civilians, seamen, and soldiers mingling indiscriminately.

It was a risky business. At any moment an exasperated Rioguayan might "let rip" with rifle or revolver, since there were no signs of anyone in authority to hold the throng in check. Yet unhesitatingly the unarmed picket-boat held on her course until at length she ran alongside the broad stone steps facing the Rioguayan Port Admiral's residence.

"Hey, laddie!" exclaimed a voice that sounded strangely familiar.

"Hello, Mackenzie!" replied Peter. "Didn't expect to see you in this galley."
