[05:24.612]The drug was administered in a drink of water given at the start of each day's exercise. [05:30.334]Twenty-five minutes later, the first effects of the drug became apparent: the men began to relax, and to giggle. [05:37.788]This man was more seriously affected, and had to be removed from the exercise. [05:42.822]After 35 minutes, one of the radio operators had become incapable of using his set, [05:48.965]and the efficiency of the rocket-launcher team was also very impaired. [05:54.044]Ten minutes later, the attacking section had lost all sense of urgency: [05:58.248]notice the bunching and indecision as they enter the wood occupied by the enemies. [06:03.660]Almost immediately, the section commander tried to use a map to find the location of troop headquarters, [06:09.021]as the prisoner's escort had to have the way pointed out, [06:12.359]though it was in plain sight 700 yards away over open country. [06:17.344]Fifty minutes after taking the drug, [06:19.347]radio communication had become difficult, if not impossible, [06:22.822]but the men are still capable of sustained physical effort. [06:26.557]However constructive action was still attempted by those retaining a sense of responsibility, despite the physical symptoms. [06:33.610]But one hour and ten minutes after taking the drug, [06:36.702]with one man climbing a tree to meet the birds, the troop commander gave up, [06:41.659]admitting that he could no longer control himself, or his men. [06:50.284]He himself then relapsed into laughter.
