Once, on Rosh Chodesh Nissan during the Rebbe’s Rosh Chodesh seuda, the tzaddik entered, looked around and declared, “I see here many soldiers have gathered; now I wish to admonish you all. Although you may be forced to eat treifos, I beg you, do not lick the bones in delight!”
The chassidim were very confused by the Rebbe’s declaration and admonishment, since only chassidim were present with not a single soldier among them. After several years, however, the First World War broke out and the draft began. Many of them indeed were conscripted into the army. It was then that the tzaddik’s pronouncement rang in their ears and his ruach hakodesh was revealed, as now they had become soldiers who were beset by the challenges the rebbe had referenced.
