Middendorf, with whom he—his name was Prohaska—had been on more intimate terms than the others, once asked him, when he timidly avoided the girls and women who cast kindly glances at him, if his heart never beat faster, and received the answer, "I have but one love to give, and that belongs to our native land."
While the battle was raging, Middendorf was fighting close beside his comrade. When the enemy fired a volley the others stooped, but Prohaska stood erect, exclaiming, when he was warned, "No bowing! I'll make no obeisance to the French!"
A few minutes after, the brave soldier, stricken by a bullet, fell on the greensward. His friends bore him off the field, and Prohaska—Eleonore Prohaska—proved to be a girl!
While in Castle Gohrde, Froebel talked with his friends about his favourite plan, which he had already had a view in Gottingen, of establishing a school for boys, and while developing his educational ideal to them and at the same time mentioning that he had passed his thirtieth birthday, and alluding to the postponement of his plan by the war, he exclaimed, to explain why he had taken up arms:
"How can I train boys whose devotion I claim, unless I have proved by my own deeds how a man should show devotion to the general welfare?"
These words made a deep impression upon the two friends, and increased Middendorf's enthusiastic reverence for the older comrade, whose experiences and ideas had opened a new world to him.
The Peace of Paris, and the enrolment of the Lutzow corps in the line, brought the trio back to Berlin to civil life.
There also each frequently sought the others, until, in the spring of 1817, Froebel resigned the permanent position in the Bureau of Mineralogy in order to establish his institute.
Middendorf had been bribed by the saying of his admired friend that he "had found the unity of life." It gave the young philosopher food for thought, and, because he felt that he had vainly sought this unity and was dissatisfied, he hoped to secure it through the society of the man who had become everything to him His wish was fulfilled, for as an educator he grew as it were into his own motto, "Lucid, genuine, and true to life."
Middendorf gave up little when he followed Froebel.
