As to the Conclusions of Leipsic, indeed, at first they gave the Imperial court some uneasiness, but when they found the Imperial armies, began to fright the members out of the union, and that the several branches had no considerable forces on foot, it was the general discourse at Vienna, that the union at Leipsic only gave the emperor an opportunity to crush absolutely the Dukes of Saxony, Brandenburg, and the Landgrave of Hesse, and they looked upon it as a thing certain.

I never saw any real concern in their faces at Vienna till news came to court that the King of Sweden had entered into the union; but as this made them very uneasy, they began to move the powerfulest methods possible to divert this storm; and upon this news Tilly was hastened to fall into Saxony before this union could proceed to a conjunction of forces.  This was certainly a very good resolution, and no measure could have been more exactly concerted, had not the diligence of the Saxons prevented it.

The gathering of this storm, which from a cloud began to spread over the empire, and from the little duchy of Mecklenburg began to threaten all Germany, absolutely determined me, as I noted before, as to travelling, and laying aside the thoughts of Hungary, I resolved, if possible, to see the King of Sweden’s army.

I parted from Vienna the middle of May, and took post for Great Glogau in Silesia, as if I had purposed to pass into Poland, but designing indeed to go down the Oder to Custrim in the marquisate of Brandenburg, and so to Berlin.  But when I came to the frontiers of Silesia, though I had passes, I could go no farther, the guards on all the frontiers were so strict, so I was obliged to come back into Bohemia, and went to Prague.  From hence I found I could easily pass through the Imperial provinces to the lower Saxony, and accordingly took passes for Hamburg, designing, however, to use them no farther than I found occasion.

By virtue of these passes I got into the Imperial army, under Count Tilly, then at the siege of Magdeburg, May the 2nd.

I confess I did not foresee the fate of this city, neither, I believe, did Count Tilly himself expect to glut his fury with so entire a desolation, much less did the people expect it.  I did believe they must capitulate, and I perceived by discourse in the army that Tilly would give them but very indifferent conditions; but it fell out otherwise.  The treaty of surrender was, as it were, begun, nay, some say concluded, when some of the out-guards of the Imperialists finding the citizens had abandoned the guards of the works, and looked to themselves with less diligence than usual, they broke in, carried an half-moon, sword in hand, with little resistance; and though it was a surprise on both sides, the citizens neither fearing, nor the army expecting the occasion, the garrison, with as much resolution as could be expected under such a fright, flew to the walls, twice beat the Imperialists off, but fresh men coming up, and the administrator of Magdeburg himself being wounded and taken, the enemy broke in, took the city by storm, and entered with such terrible fury, that, without respect to age or condition, they put all the garrison and inhabitants, man, woman, and child, to the sword, plundered the city, and when they had done this set it on fire.
