The ship’s scheduled departure meant that it would be on the high seas on Yom Kippur

IN the spring of 1941, Admiral Isoroku Yamamoto was authorized by the general staff of the Imperial Japanese Navy to begin operational planning for a massive attack on the US Naval Headquarters at Pearl Harbor. The success of the operation hinged on keeping it secret. To that end, the Japanese government had concerns about potential espionage among the throngs of foreign refugees temporarily housed on the Japanese home islands since the previous year.
Thousands of Jews fleeing Soviet-occupied Lithuania had received Japanese transit visas and had not been able to continue their journey to a final destination. The Japanese government decided to unceremoniously dump the refugees in Japanese-occupied Shanghai, China, until further notice. Upon arriving there in the summer and fall of 1941, most refugees had no illusions about a long-term arrangement of a Chinese sojourn, and they desperately sought routes to a final destination such as the United States.
After much wrangling, the Joint Distribution Committee was able to secure 41 visas for members of the yeshivah community among the refugees, as well as transport on the SS President Pierce, which was set to depart Shanghai for San Francisco at the end of September 1941. This would be a fateful journey; two months later, hostilities would break out between Japan and the United States, and there would be no trans-Pacific crossings for five years. The refugees who succeeded in departing on the President Pierce would be the last ones to leave Shanghai until after the war.
Although 12 members of the Mir Yeshivah received passage on the steamer, thereby ending their stay in Shanghai, they chose not to take this route. Their reasoning — as articulated by the leader of the group, Rav Leib Malin — was twofold.
The ship’s scheduled departure meant that it would be on the high seas on Yom Kippur, in an area where the location of the halachic international dateline was subject to doubt. This would necessitate observing Yom Kippur for two days. In addition, Rav Leib felt that it would be preferable for the yeshivah to remain together during this time of crisis, especially for the duration of the High Holiday season. Because they weren’t privy to the Japanese Navy’s plans, they assumed they could simply take the next steamer across the Pacific.
The Mir group’s sudden last-minute cancellation elicited much-justified resentment from other refugee groups, as those 12 difficult-to-obtain berths were now wasted, unfilled on what would be the last trans-Pacific crossing until after World War II. But for the 29 members of the yeshivah community who did sail aboard the SS President Pierce, it would be a journey of salvation, rescuing them from the Shanghai exile, with the promise of a better future on the other side of the world.
