During World War Two, there was a massive explosion a few miles off the shores of the Gulf of Mexico. It rocked Galveston, Texas City and towns nearby. No ships were reported sunk - nothing is shown in the military records from that period. What was it? Was it another of the many U-boat victims of the Drumbeat campaign? Was it due to the hurricane that struck the coast around that time? - or was it caused by something else? __________________________________________________ Distant Thunder, an action-packed story laced with historical facts, follows the experiences of an elite German unit - whose mission, if successful, could alter the course of the war - and with it the history of the world.
