Frederick had now under his command twenty-four thousand men. They were mostly on the road between Frankfort and Berlin, for the protection of the capital. His brother Henry, in the vicinity of Landshut, with his head-quarters at Schm?ttseifen, was in command of thirty-eight thousand. The Russians and Austrians numbered one hundred and twenty thousand. There was, however, but little cordial co-operation among the allies. Each was accused of endeavoring to crowd the other to the front of the battle against the terrible Frederick.
Frederick deemed it of great importance to gain immediate possession of Glogau. It was bravely defended by the Austrian commander, Count Wallis, and there was hourly danger that an Austrian army might appear for its relief. Frederick, in the intensity of his anxiety, as he hurried from post to post, wrote from every stopping-place to young Leopold, whom he had left in command of the siege, urging him immediately to open the trenches, concentrate the fire of his batteries, and to carry the place by storm. I have clear intelligence, he wrote, that troops are actually on the way for the rescue of Glogau. Each note was more imperative than the succeeding one. On the 6th of March he wrote from Ohlau:
In the cold of the winter morning the Old Dessauer carefully reconnoitred the position of his foes. Their batteries seemed innumerable, protected by earth-works, and frowning along a cliff which could only be reached by plunging into a gully and wading through a half-frozen bog. There was, however, no alternative but to advance or retreat. He decided to advance.I rely upon your zeal and hearty concurrence to support the King of Prussia and the rest of my allies, and to make ample517 provision for carrying on the war, as the only means of bringing our enemies to equitable terms of accommodation.
