Factual error: Secretary of State John Hay is depicted issuing the order to "initiate hostilities" against Spain. Unfortunately, at the time we actually went to war with Spain, John Hay was not the Secretary of State. That position was held by William. R. Day. Hay did not become SofS until September of 1898, after most hostilities had ended.
Factual error: The women have been starving in a Japanese prisoner of war camp for 3 years but seem to have suffered no physical ill-effects other than a healthy suntan and a fetching crop-style haircut. In the fight-in-the-shower scene (yes boys, this is nearly as good as it sounds) you get to see an array of perfect bodies with no sores, bruises, blisters, sunburn or any other signs that they have been doing hard labour under the blazing sun and seriously deprived of vitamins. At the end when they keep dying of starvation they're all just as plump and healthy as ever.
