Mr. BLALOCK. Yes, sir; he did, and he explained that he took training in guerrilla warfare, and he told us how to blow up bridges, derail trains, make zip guns, make homemade gunpowder. Mr. LIEBELER. He told you about this in detail? Mr. BLALOCK. He told us how to blow up the Huey P. Long Bridge. Mr. LIEBELER. Tell us just what he told you about that. I know you can't remember the exact words, but you can remember the substance of the conversation. We want you to tell us about it. Mr. BLALOCK. He told us to put powder charges at each end of the bridge from the foundation to where the foundation meets the suspension part, and to blow that part up and the center part of the bridge would collapse. Mr. LIEBELER. Did he talk about any other aspect of guerrilla warfare that you can remember? Mr. BLALOCK. He said that if you don't have the materials you need always available, you had to do without stuff. Mr. LIEBELER. Did he give any specific example of that? Mr. BLALOCK. Gunpowder, high explosives. Mr. LIEBELER. Did he tell you how to do without gunpowder in these activities? Mr. BLALOCK. He told us how to derail a train without gunpowder. Mr. LIEBELER. What did he say about that? Mr. BLALOCK. He said put a chain around the railroad track and lock it to the track with a lock. Mr. LIEBELER. And then when the train hit the chain it would derail the train? Mr. BLALOCK. Yes, sir. Mr. LIEBELER. Did he say that he knew how to make gunpowder? Mr. BLALOCK. Yes, sir; he told us the formula, and I--saltpeter and nitrate--some formula--I don't remember. Mr. LIEBELER. Did he say anything about guns? Mr. BLALOCK. About zip guns, how to make them out of tubing and a plunger. Mr. LIEBELER. Did he say something to the effect that he knew all about guns? Mr. BLALOCK. No; he told us he had a manual that explained all about guns, a Marine manual, and that he had training in guns, trained with guns. Mr. LIEBELER. Do you remember anything else that he said? Mr. BLALOCK. Not right offhand. Mr. LIEBELER. Did he talk to Bringuier about helping Bringuier in this organization, or just what was the general context of this conversation? Was this just a general discussion of guerrilla warfare, or did it relate to the activities of Bringuier's anti-Castro organization? What can you remember? Mr. BLALOCK. He just asked him about the anti-Castro organization and asked him to explain it to him, and he said he was interested in finding out how it operated. He didn't say he wanted to join it: He just said he was interested in it. Oh, and Bringuier gave him literature, a Cuban newspaper and leaflets or booklets. Mr. LIEBELER. Was there any discussion of politics? Mr. BLALOCK. Not to my recollection. Mr. LIEBELER. Was there any mention of President Kennedy? Mr. BLALOCK. No, sir. I couldn't say for sure there was no mention of President Kennedy. I don't think there was. Mr. LIEBELER. What did you think of Oswald?
