observation tower at Cape Henlopen, Delaware

After Rockville, Maryland, we continued on our FFF (Family and Friends Fall) Road Trip to Bethany Beach, Delaware, where my brother and his wife have recently purchased a home. 

We love these concrete observation towers along the Delaware coast. Built from 1939 to 1942 to guard the entrance to Delaware Bay after world war broke out in Europe, there are eleven on the Delaware coast and two across the bay in New Jersey. They were built to last only 20 years, but are still standing after almost 80. (And, yes, I did go up in one, despite the rusty old stairs.)

German ships were a real threat to American shipping even before we were directly involved in the war. When the Luftwaffe was unsuccessful in defeating the Royal Air Force with its eleven-month campaign of daily air attacks against the UK (the Battle of Britain), Hitler shifted gears and imposed a naval blockade in the Atlantic, hoping to starve the British into surrender. German U-boats and destroyers patrolled off the US Atlantic coast looking for American ships headed to Britain that may contain relief supplies.

These towers are a poignant reminder, especially now that our Greatest Generation is almost gone, of the sacrifices Americans were asked to make to defend their homeland. I hope they last another eighty years. Thank you, Delaware, for honoring the memory of those who served.
