Large autograph leaf (written on both sides), copies of letters by R. Abraham Isaac Kook (later, Chief Rabbi of Eretz Israel), written during his stay at S. Gallen, Switzerland, 1915, in the course of WWI. Some letters have never been printed.

Apparently, these letters were copied by his son R. Zvi Yehuda Kook. Some of the letters deal with halachic matters and Torah thoughts and others with public matters and personal and family issues.

This leaf contains:
• Copy of a letter dated 17 Shevat 1915, addressed to his parents, explaining the necessity of remaining in Switzerland and his yearning to assist his brethren and the lack of sustenance due to the war situation. The letter also contains Torah thoughts. To the best of our knowledge, this letter has never been printed.
• Copy of a letter dated 21 Shevat 1915, to R. Zeev Rom, about personal matters, with a Torah responsum. Printed in Igrot Hara'ayah Part II, Chapter 716; the halachic part was also printed in Responsa Daat Cohen, Chapter 5.
• Copy of a letter dated 20 Shevat 1915, letter of inspiration to Jews banished by the Ottomans to Alexandria, Egypt at the beginning of WWI. After his signature, R. Kook inquires as to the welfare of his dear friend R. M. Lazerowitz, son-in-law of R. Zalman Shach and as to the wellbeing of his friend R. Slutzkin. The main content of the letter was printed in Igrot Hara'ayah Part II, Chapter 715, however, the addition with his regards was not printed.
• Copy of a letter dated 24 Shevat 1915, to R. Aryeh Dov Ritter, rabbi of Rotterdam, a friend of R. Kook – a long letter regarding assistance to Torah scholars and institutes in Eretz Israel during the war. To the best of our knowledge, this letter has not been printed.
