Through June and up to the middle of July, however, no very evil consequences were apparent. On the 21st of July two divisions of French troops under General Canrobert marched into the Dobrudscha, in search of some bodies of Russians who were said to be there. On the night of the 28th cholera broke out, and before morning, in one division no less than 600 men lay dead. The other divisions, although situated at considerable distances, were simultaneously attacked with equal violence, and three days later the expedition returned, having lost over 7000 men. Scarcely less sudden or less fatal was the attack among the English lines, and for some time the English camps were ravaged by cholera. Jack was extremely anxious about his brother, for the light division suffered even more severely than did the others. But he was not able to go himself to see as to the state of things, for the naval officers were not allowed to go on shore more than was absolutely necessary. And as the camp of the light division had been moved some ten miles farther away on to the slopes of the Balkans, it would have been impossible to go and return in one day. Such precautions as were taken, however, were insufficient to keep the cholera from on board ship. In a short time the fleet was attacked with a severity almost equal to that on shore, and although the fleet put out to sea, the flagship in two days lost seventy men. Fortunately the "Falcon" had left Varna before the outbreak extended to the ships. The Crimea had now been definitely determined upon as the point of assault. Turkish vessels with heavy siege guns were on their way to Varna, and the "Falcon" was ordered to cross to the Crimea and report upon the advantages of several places for the landing of the allied army. The mission was an exciting one, as beside the chance of a brush with shore batteries, there was the possibility that they might run against some of the Russian men-of-war, who still held that part of the Black Sea, and whose headquarters were at Sebastopol, the great fortress which was the main object of the expedition to the Crimea. The "Falcon" started at night, and in the morning of the second day the hills of the Crimea were visible in the distance. The fires were then banked up and she lay-to. With nightfall she steamed on until within a mile or two of the coast, and here again anchored. With the early dawn steam was turned on, and the "Falcon" steamed along as close to the shore as she dare go, the lead being constantly kept going, as but little was known of the depth of water on these shores. Presently they came to a bay with a smooth beach. The ground rose but gradually behind, and a small village stood close to the shore.
