Journey to the West (Xiyouji, 西遊記, 1592; “JTTW” hereafter) chapter 98 sees the pilgrims sent back to China on a cloud to hasten the completion of their mission and subsequent return to paradise. However, shortly after their departure, Guanyin realizes in chapter 99 that Tripitaka has only experienced a total of 80 tribulations during his life, which is just shy of the perfect, sacred number (9 x 9 = 81). Therefore, she orders the eight Dharma guardians piloting the cloud to prematurely drop them off somewhere before reaching their stated destination. Sha Wujing reasons that this was done because they are going too fast (Wu & Yu, vol. 4, pp. 357-361).
The companions find that they have been deposited along the western bank of the “Heaven-Reaching River” (Tongtian he, 通天河), the same body of water where a giant, white turtle-spirit (baiyuan, 白黿) had ferried them across in chapter 49 (fig. 1). This same reptile appears and offers to carry them to the eastern bank (i.e. in the direction of China), but when he learns that the clerics had failed to keep their promise to ask the Buddha when the turtle’s long years of cultivation would result in him achieving human form (Wu & Yu, 2012, vol. 2, pp. 359), the angry spirit dives into the water, dunking the clerics, the dragon horse, and the hard-won scriptures. Thus, the 81st tribulation is achieved (Wu & Yu, 2012, vol. 4, pp. 362-363).

This episode is likely based on a historical accident that resulted in the real Xuanzang (玄奘, 602–664) (on whom Tripitaka is based) losing 50 scriptures to the drink. I first learned about the real world event from Brose (2021) and made the connection to JTTW chapters 98 and 99 on my own. Here’s a twitter post from 2022 attesting to that. But when I recently revisited the idea for a possible article, a cursory search didn’t turn up much information about the accident in Xuanzang’s historical travelogue, A Biography of the Tripitaka Master of the Great Ci’en Monastery (Datang Daci’en si Sanzang Fashi Zhuan, 大唐大慈恩寺三藏法師傳, 7th-century; T2053; “A Biography” hereafter). Luckily, I found the answer in Brose (2023), where he states: “Xuanzang does not recount the accident in his Record; he mentions it only briefly in the letters he later wrote to monks in India requesting copies of the lost texts” (p. 147). The provided citations led me to the correct sections of A Biography.
The end of one letter presented in scroll seven (of ten) reads:
[…] Of the scriptures and commentaries that I have brought back, I have already translated the Yogācārabhūmi Śāstra and other long and short texts, making a total of over thirty works. The translation of the Abhidharmakośa Śāstra and the Abhidharmanyāyānusāra Śāstra is not yet completed, but it will be finished this year. The reigning Emperor of the Great Tang Empire is enjoying every felicity, with peace prevailing throughout his land. With the compassion of a Cakravartin King, he has spread the edification of the Buddha, composed a preface with his Divine Pen to all the Chinese translations of the scriptures and commentaries, and also ordered the authorities to copy them for circulation in the country. Thus even neighboring states also follow and study them. Although we are now at the end of the Image Period, the brilliance of the Dharma is still as genial and as glorious as when it was taught in the Jetavana Garden in Śrāvastī. I hope you will take note of the above information. When I was crossing the Indus [on my way back home], I lost a pack of scriptures (emphasis added). I am now sending you herewith a list of the lost texts, of which I request that you send me new copies by some convenient messenger (Huili & Shi, 1995, pp. 232-233).
玄奘所將經論,已翻《瑜伽師地論》等大小三十餘部,其《俱舍》、《順正理》,見譯未周,今年必了。即日大唐天子聖躬萬福,率土安寧,以輪王之慈,敷法王之化,所出經論,並蒙神筆製序,令所司抄寫,國內流行,爰至隣邦亦俱遵習。雖居像運之末,而法教光華,邕邕穆穆,亦不異室羅筏誓多林之化也,伏願照知。又前渡信渡河失經一馱,今錄名如後,有信請為附來。(source)
This is admittedly anticlimactic, but a fuller, more exciting version of the event appears in scroll five:
After travelling for more than twenty days, he reached the country of Takṣaśilā and revisited the place where King Candraprabha had sacrificed his head a thousand times in his previous lives. Fifty yojanas to the northeast of this country was the country of Kaśmīra. The king sent an envoy to invite the Master [i.e. Xuanzang]; but as he was riding on an elephant and had luggage with him, he was unable to go. After staying there for seven days, he proceeded northwest again for three days and reached the great Sindhu [i.e. Indus] River, which was five or six li broad. His scriptures and images were loaded in a boat with his companions to sail across the river, while the Master waded through the river on his elephant [fig. 2]. He had appointed a man in the boat to take care of the scriptures and some seeds of different kinds of rare Indian flowers. When the boat sailed to midstream, a turbulent gale suddenly arose. The waves tossed the boat and almost overturned it. The man who was asked to look after the scriptures was so frightened that he fell overboard, but was rescued by the other passengers. Fifty bundles of scriptures and flower seeds were lost, while his other property narrowly escaped damage.
At that time the king of Kapiśā who was already in the city of Uḍakhāṇḍa heard that the Master was arriving and went personally to the riverside to greet him. He inquired, “I heard that you lost your scriptures in the river. Did you bring any seeds of Indian flowers and fruits with you?” “Yes, I did,” was the reply. The king said, “That was the cause of the gale that stirred up the waves and almost overturned your boat. Since ancient times, those who brought flower seeds to cross this river have always had the same trouble.” Then he returned to the city with the Master, who lodged in a monastery for more than fifty days. As he had lost some of his scriptures, he sent a man to the country of Udyāna to copy the Tripiṭaka of the Kāśyapīya school (Huili & Shi, 1995, pp. 156-157).
如是二十餘日行,至呾叉尸羅國,重禮月光王捨千頭處。國東北五十踰繕那即迦濕彌羅國,其王遣使迎請,法師為象行輜重不果去。停七日,又西北行三日至信度大河,河廣五六里,經像及同侶人並坐船而進,法師乘象涉渡。時遣一人在船看守經及印度諸異花種,將至中流,忽然風波亂起,搖動船舫,數將覆沒,守經者惶懼墮水,眾人共救得出,遂失五十夾經本及花果種等,自餘僅得保全。
時迦畢試王先在烏鐸迦漢茶城,聞法師至,躬到河側奉迎,問曰:「承師河中失經,師不將印度花果種來?」答曰:「將來。」王曰:「鼓浪傾船,事由於此。自昔以來,欲將花種渡者,並然。」因共法師還城,寄一寺停五十餘日,為失經本,更遣人往烏長那國抄寫迦葉臂耶部三藏。(Source)
And lastly, scroll two associates the Indus River with greedy water-spirits that capsize boats in order to gain the treasures therein:
From the city of Uḍakhāṇḍa, the Master crossed the Indus to the south. The river was three or four li wide, and the water was very clear and flowed rapidly. Many venomous dragons and evil animals dwelt in it. Anyone crossing the river with Indian precious gems, rare flowers, or relic bones would often have his boat overturned (Huili & Shi, 1995, p. 60).
自烏鐸迦漢茶城南渡信渡河,河廣三四里,流極清急,毒龍惡獸多窟其中,有持印度奇寶名花及舍利渡者,船輒覆沒。(source)
Connecting the three passages presents a complete picture of the event: Xuanzang and his servants attempted to cross the Indus River with precious scriptures and the seeds of rare Indian flowers, but one or more river dragons called up a powerful wind that capsized the boat carrying his treasures just so it/they could get their scaly mitts on them. This/these beast(s) and their crime eventually made it into the 1592 JTTW in the form of the giant white turtle-spirit and his grudge against the scripture-seekers.

Maria Josey, a friend of the blog, told me that she saw a statue of the pilgrims riding the turtle in a temple from Phuket, Thailand (fig. 3). She explains:
This story featured heavily in the chosen design of the temple grounds … [T]he monument is quite high up, on a mound, then a huge boulder. Cannot have been easy to build, I imagine, but it must have meant a lot to whoever did make it.
