In the midst of his irritation against Prussia and her envoy, Thugut heard with astonishment the British proposals, presented at Berlin early in February, to bring 100,000 Prussians into the field. Urgently he remonstrated with Eden, pointing out that Prussia had played them false in two campaigns, and would do so again, witness her late contention that France must not be weakened. On no account, then, must Frederick William head a compact mass of 100,000 men in the Palatinate. He would be the arbiter of the situation. He would be between the Austrian army in Brabant and the Hapsburg States. Nay, he might march into Swabia, reach the Danube, take boats at Ulm, and, sailing down that stream, have Vienna at his mercy![343] So pressing were these anxieties that, at the close of February, Thugut sent a special request to Catharine II to guarantee the security of Austria's possessions in case Frederick William withdrew from the Coalition. Despite the utmost efforts of the British Ministry and its envoys, no plan of vigorous co-operation could be arranged between the two German rivals; the sole link connecting them was the clause of the treaty of 1792, whereby Austria, as having been attacked by France, claimed the help of 20,000 Prussians. Frederick William decided that this force must remain at Mainz, in order to guard the Empire from a French raid. He promised 80,000 more troops to Great Britain and Holland, provided that they were paid for. On one point alone the four Allies came near to agreement, namely, that the main Prussian army should operate in Flanders, so as effectively to defend the Dutch territory, secure conquests in the North of France, and, above all, preclude the quarrels which must ensue if it acted near the Austrians.[344] Thugut of course assented, his great aim being to remove the Prussians as far as possible from Swabia. Disputes on these subjects went on up to the end of March 1794, the time when an advance into French Flanders promised great results. The reader will naturally ask--Can this be called a Coalition? A Coalition implies some power of coalescing. But among the four Powers there was far more of disunion than union. In fact, England was the sole link between these wrangling confederates, and that, too, solely by means of what Carlyle called the cash nexus. Grenville, using a more homely metaphor, averred that the German princes turned towards England as an inexhaustible milch-cow. The animal in this case could dictate her terms; and thus the relations of the three Powers resembled those of a rich but somewhat exigent employer to grumbling and distrustful employees. Holland also, in return for her sacrifices in men and money, demanded from Austria a better frontier on the side of Dutch Flanders and Maestricht, to which the Viennese Court opposed a quiet but firm resistance.
