During their years in prison they wrote regularly to their families. An exceptionally rich correspondence was found in May 1942 among the things Franek and Edek sent home after sorting out their possessions shortly before leaving Neuhlln. They wrote of their feelings and prison anecdotes and while not hiding their homesickness they sparkled with wit. They asked about their kin, not forgetting even the shoemaker in the next street. They wrote feelingly about their plans for the future.

These young men, confined for months in prison cells, did not indulge in self-pity, did not revolt, did not harbour hatred - they worried about their families and friends who were still at liberty. It was a strange paradox, the imprisoned comforted the free, the hungry the relatively well fed.

“Darling Mama what can I say to comfort you,” Kazmlerski asked in his letter of March 1942, “everything is in the hands of God. Nothing happens without Him. I can always feel Him watching over me. God is with us. He gave us the cross and he will give us strength to carry it.”

In a letter of May 8th, 1942 he wrote “If only you were not worried about the future. Our only worry is that you worry." "How much I owe you”, Kazmlerski said to his mother, “above all that you taught me the principles of our Holy Faith. What strength it is. There are some here who do not believe in anything. One hears only profanity and abuse. In those whose faith is strong there is peace, and instead of profanity real happiness.

Even Kamierski, whose letters were so witty, became sad when writing to his mother. "Nearly everything is ready to pack,” he wrote to her on May 11th 1942. “Our cell looks like a prison now and we miss the picture of Saint John Bosco over the door, but we have it hidden under our shirt and God grant that they will not be taken from us. I still have your photo and your image will never be erased from my heart, I can't write cheerfully to you, to others I somehow can. The longing is too great and I have a sense of guilt "

The young men wrote many heartfelt words to other members of the family. "Darling Dad, today is your name day, the second one that I am not with you. Today our prayers to God were for your intentions that God will bless you." were Franek Kesy’s words. And when he heard that there was the danger of his sister being transported to Germany for forced labour, he tried to comfort her as much as he could. He was prepared to take her suffering on himself, “I pray to God that I and not you should be given all the worry and suffering,” and regretted that, “somehow God does not want to listen to me.” Further on he said, “I did not know that I could love you so much. Until I got your letter and learnt that you too are in trouble."

A moving expression of brotherly affection is Edek letter to his youngest sister Ulka who had curvature of the spine. It in worth quoting in brief: “My dearest Ulka! I have only written one page and it is already dark. I can hardly see to write, and tomorrow we must pack. I must get up early and write you a bit more, so that you won't think that I don't want to. Meanwhile - goodnight! May God protect you!” “Tuesday already - all quiet as it is only 5.30 am. I must finish this letter because we shall have to pack after breakfast. We are going by the first transport today to Zwickau. Pray that It will be as good there as it is here, God will surely listen to you, how's your work going? What do you think, when will we go for a bicycle ride together? Sometimes I would like so much to go right away, that I can hardly stand it. But no it will come in time.

Have you still got any friends or have they all forgotten about you as mine have? But don't worry this will pass like a film in the cinema. Right now it is enough that you all love me so much. You can be sure Ulka, that I do love you very much.”

They were optimistic - Edek and Franek. Even the news of the trial did not worry them. They took it their stride. “Our trial in coming up soon”, Edek Kamierski wrote to his sister Maria, “but I don't believe it, they have been talking about the trial for almost two years.” Franek Kesy was of the same opinion. "Our trial is nothing to worry about,” he assured his family, "It looks frightening but it's not so bad. We laugh at it.” Franek was more concerned about his friend Jarek, whose mother had died but whose sister had kept the truth from him. "It is bad that his sister lied to him about his mother's death," we read in Franek Kesy's letter, "Poor fellow, he's probably praying for her recovery and she has been dead for over a year. It's terrible.” Finally, after several months Lydia wrote and told him the truth. Jarek took it like a Christian and a man, "Your last letter brought me the painful news that God has called our beloved mother,” he wrote in reply to her letter? “Even though for us there will always be a shadow on this world, we must live and praise God, because it is His will. I am resigned and do not grieve. Just before my arrest I was prepared for this; that we would not have Mama with us for long. I have had the impression that some weeks ago something happened to Mama." He now had only his sister who, as he wrote in his letter, he "loved too quietly, which means only in my heart but not in deeds.” He promised, however “that in future it will be different.”

“My beloved Parents and Brothers and Sisters,” Franek Kesy's letter begins, "the time to say farewell to you has come, today August 24th the day we think of Mary Help of Christians, the Good God takes me to Himself. Do not regret that I leave this world at such a young age. I am now in a state of grace, and do not know if I would later have been faithful to my determination to get to heaven, till we meet there. Pray for me sometimes.”

The next day on the walls in Pozna there appeared a sinister red poster proclaiming that the high court in Pozna had condemned to death the Poles listed on the poster. They were accused of conniving to high treason. The sentence was carried out on August 24th 1942. Among the eight victims were five members of the Salesian Oratory in Wroniecka Street, Pozna, Poland
