The next three weeks passed pleasantly, Jack spending all his time, when he could get leave, with his brother, and the latter often coming off for an hour or two to the “Falcon.”  Early in May the news arrived that the Russians had advanced through the Dobrudscha and had commenced the siege of Silistria.  A few hours later the “Falcon” and several other ships of war were on their way up the Dardanelles, convoying numerous store-ships bound to Varna.  Shortly afterwards the generals of the allied armies determined that Varna should be the base for the campaign against the Russians, and accordingly towards the end of May the troops were again embarked.

Varna is a seaport, surrounded by an undulating country of park-like appearance, and the troops were upon their arrival delighted with their new quarters.  Here some 22,000 English and 50,000 French were encamped, together with 8,000 or 10,000 Turks.  A few days after their arrival Jack obtained leave for a day on shore, and rowed out to Alladyn, nine miles and a half from Varna, where the light division, consisting of the 7th, 19th, 23d, 33d, 77th, and 88th regiments, was encamped.  Close by was a fresh-water lake, and the undulated ground was finely wooded with clumps of forest timber, and covered with short, crisp grass.  No more charming site for a camp could be conceived.  Game abounded, and the officers who had brought guns with them found for a time capital sport.  Everyone was in the highest spirits, and the hopes that the campaign would soon open in earnest were general.  In this, however, they were destined to be disappointed, for on the 24th of June the news came that the Turks had unaided beaten off the Russians with such heavy loss in their attack upon Silistria that the latter had broken up the siege, and were retreating northward.

A weary delay then occurred while the English and French home authorities, and the English and French generals in the field were settling the point at which the attack should be made upon Russia.  The delay was a disastrous one, for it allowed an enemy more dangerous than the Russians to make his insidious approaches.  The heat was very great; water bad, indeed almost undrinkable, the climate was notoriously an unhealthy one, and fruit of all kinds, together with cucumbers and melons, extremely cheap, and the soldiers consequently consumed very large quantities of these.

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.
