    .. and so, I went aboard this Sub Chaser. No they didn't go under the water. At least not on purpose they didn't. Sure we had guns. A 40 mm and two 20 mm. You have heard of depth chargers but how about Mouse Traps? Well they were little rockets that set on launching ramps and were fired by electricity. Oh they would go about the length of a football field. Yah they were a good idea but I doubt that they were ever used. You see they had to be armed and the little ground wire broken, which means the sub had to be slower than your SC.

    I'm glad you asked, son. We went into the Charleston Navy Yard. No the one in Boston Harbor. Don't interrupt now.

    We had broken the socket for our jack staff - that's the flag that's blue with white stars-I don't know, why but any way the socket sat on top of the bull nose that's right, just like on our sail boat. Well to make a long story -ok I will. Don't interrupt.

    The welder that they sent brought an electric welding machine with him. He clamped his ground wire to the flashing and struck on the bull nose. You're right. Only three took off, right over his head. They went about a hundred yards where they hit a brick wall. No, he didn't seem to be hurt but it drew a crowd especially Union stewards. The powers that ran the yard directed us to proceed to the ammo dump where we unloaded all our depth charges, etc. returned to the Yard where they brazed the socket back in place and then back and reloaded our ammo. Yes they replaced the rockets.
