Neither Naples nor Austria ventured on overt action in behalf of the Pope; but the dissatisfaction of both was extreme. Never under Bonaparte himself had French troops come so near to the kingdom of the Two Sicilies, whose importance to the common cause of the Continent, from its geographical position, was perfectly understood. But while the situation of Naples at the far end of the peninsula made it a serious danger to the flank and rear of the French, when engaged with an enemy in upper Italy, its remoteness from support, except by way of the sea, was a source of weakness to a state necessarily dependent upon allies. This was especially felt in February, 1798, when the British fleet, after a year's absence, had as yet given no sign of returning to the Mediterranean, and the ships which accompanied Bonaparte to Egypt were still in Toulon. The latter would doubtless have been directed upon Naples, had Naples moved against Rome. The Bourbon kingdom therefore swallowed its vexation, but drew closer to Austria; which, in addition to the affront offered to the Pope, had its own motives for discontent in the occupation of Switzerland by the French, and in the changes introduced into the political complexion of the Continent by these aggressive actions of the republican government. The course of the Directory during the continental peace of 1797 and 1798 was closely parallel to that of Bonaparte four years later, which made impossible the continuance of the Peace of Amiens. With less ability and less vigor, there was the same plausible, insidious, steady aggression, under color of self-protection or of yielding to popular demand, which forced on the power of France at the expense of other states. An occurrence in Vienna at this moment came near to produce war and stop the Egyptian expedition. When Bonaparte entered Germany in April, 1797, the youth of Vienna had offered themselves in mass to defend the country. In April, 1798, the anniversary of the day was celebrated with a popular demonstration, which the French ambassador resented by hoisting the tricolor. The crowds in a rage broke into and sacked the embassy.[212] So great was the excitement over this affair that the troops in Toulon and other ports were ordered not to embark, and Bonaparte himself was directed to go as plenipotentiary to Rastadt; but the emperor made explanations, and the incident passed. Still, as a French historian says, "things were getting spoiled between Austria and France."[213]
