Final answer:
While the provided text does not specify an exact figure, historical records have shown that Patriot POWs were significantly more likely to die in prison ships than in battle, with some estimates indicating a figure as high as 11 times more likely.
Step-by-step explanation:
The question relates to the conditions faced by Patriot POWs during the Revolutionary War, particularly those that were held on prison ships. Records from the time suggest that the mortality rate for Patriot POWs on these ships was incredibly high, due in part to the horrific conditions, including overcrowding, lack of sanitation, and inadequate food and medical care. Consequently, it has been estimated that Patriot POWs were about 11 times more likely to die on prison ships than in battle. However, this specific statistic seems absent from the provided information, so an exact answer cannot be given based on this text alone.
