‘Operation Drumbeat’ is a good account of the early days of German submarine warfare off the east coast. It only took a handful of German subs to wreak havoc. At one point all oil shipments were stopped due to u-boats sinking so many tankers.
Right!!
That was indeed close to home!
Unless I missed it, there was no mention of how deep the wrecks were. I, and a thousand other divers, would be interested.
In some parts of the North Carolina coast, you can still see the concrete foundations of the towers erected for surveillance of the coastal waters for German U-boats.
Early in the war on the Outer Banks of North Carolina, there was some degree of foraging/pillaging and at least one saboteur. Germans were coming ashore at night, to the extent that residents were using blackout curtains.
German submarine U-576 was a Type VIIC U-boat of Nazi Germany’s Kriegsmarine during World War II. She carried out five patrols, sinking four ships of 15,450 GRT and damaging two more of 19,457 GRT. She was sunk in July 1942 by depth charges from two US aircraft and gunfire from a merchant ship, near the East Coast of the United States. The wreck was discovered in August 2014.

That is an understatement. And lets hope that if and when it happens again, and it will, that we will have the same resolve and determination as those who fought during WWII.
