If the cause of Queen Maria Theresa was to be saved, it was evident that great efforts were imperative in the coming campaign of 1747. To meet the vast numbers brought into the field by the French the Austrians promised to have sixty thousand men at Maseyck on the Meuse by April; the British contributed four regiments of cavalry and fourteen battalions of infantry; and it was hoped that the Allies would take the field with a total strength of one hundred and ten battalions, one hundred and sixty squadrons, and two hundred and twenty guns, besides irregular troops, the whole to be under command of the Duke of Cumberland.[230] Unfortunately the weather was adverse to an early opening of the campaign; and the French, by the seizure of Cadsand and Sluys, which were shamefully surrendered by the Dutch, closed the southern mouth of the Scheldt below Antwerp. This was a sad blow to the arrangements for the transport of the Allies, since it brought about the necessity of hauling all the forage for the British overland from Breda. Had Cumberland been in a position to open the campaign before the French, he meant to have laid siege to Antwerp; as things were, he was compelled, thanks chiefly to the apathy of the Dutch, to attempt to bring Saxe to a general action. His last letter before beginning operations has, however, an interest of another kind. It contains a recommendation that Major James Wolfe may be permitted to purchase a vacant lieutenant-colonelcy in the Eighth Foot, that officer having served constantly and well during the past two years as a major of brigade and proved himself capable and desirous to do his duty.[231] [Sidenote: May 15/26.] [Sidenote: June 15/26.] [Sidenote: June 18/29.] [Sidenote: June 19/30.] [Sidenote: June 20/July 1.]
