Seventy-Five Years Ago: Tragedy on the Tow Way

Within the picture files of the Hampton Roads Naval Museum are photographs from World War II that remained classified until 2009.  At first glance, they might look like pictures taken after the attack upon Pearl Harbor.  Surrounding a huge crater on one side, fires rage out of control within the blackened skeletons of hangars with the gnarled and twisted remains of aircraft nearby, while on the other side, other fires smoulder from within the piles of timbers that were once barracks and chow halls. 
A group of officers (center) including Rear Admiral (upper half) Herbert F. Leary, who had replaced Adm. Manley H. Simons as commandant of the Fifth Naval District in May 1943, along with his chief of staff, Captain E.C. Raguet, observe rescue and recovery efforts at Chambers Field with his staff after an accidental explosion of aerial depth bombs at Naval Air Station Norfolk on September 17, 1943.

Looking south-southwest, Sailors attempt to move a station wagon that had driven into the crater left by a massive explosion of 24 aerial depth bombs that were in transit from Pier 2 of Naval Operating Base Norfolk to a magazine area on the far side of the east runway complex.  Several World War I-era barracks and a Chief Petty Officers' club in the background were reduced to splinters, while a newer brick fire station (R-43, also known as Fire Station 2) had most of its windows blown out.

As emergency personnel arrive, three casualties of the explosion at the southeast corner of Chambers Field at NAS Norfolk lie where they were felled by shrapnel from the explosion. Note the holes torn into the cowling of the TBF Avenger they were working on. The body of a dog caught by the explosion is obscured by the detached bomb bay door in the photograph.  (Hampton Roads Naval Museum file)
On a nearby aircraft ramp in front of the hangars, the bodies of Sailors lie where they had been standing moments before, felled in an instant by a wall of shrapnel that pierced the aircraft they were standing under as though they were made of paper.

The shock wave of the explosion has clearly stove in the side of the Avenger and blasted way most of the canopy.  A dog that was standing under the aircraft still lies where it fell.  An unknown number of animals died in the blast. (Hampton Roads Naval Museum file)

Although these photographs might look like they were taken in the aftermath of a devastating enemy attack, these pictures were not taken to document the carnage wrought by an enemy.  They were taken in the aftermath of a horrible accident that occurred near the main flight line of Naval Air Station Norfolk, right in the middle of Hampton Roads.
On the far side of the Avenger from the explosion site, a piece of shrapnel has torn clean through the center pontoon of a Curtiss SOC3 Seamew.  Thirty-three planes were affected by the blast, among those six were beyond repair, 15 required major overhaul and 12 were slightly damaged.(Hampton Roads Naval Museum file)
Friday, September 17, 1943, started out  as a normal day at busy NAS Norfolk. Besides preparing American and Allied air wings for the complicated business of carrier-based combat, antisubmarine patrols constantly transited NAS Norfolk to scour thousands of miles of the open Atlantic for U-Boats that continued to threaten the east coast.  The threat had significantly abated from the year before, when the German submarines taking part in Operation Paukenschlag (Drumbeat) had attacked merchant shipping just off coastal Virginia and North Carolina virtually unopposed.  Navy destroyers and Coast Guard cutters equipped with secret radio direction-finding equipment and bristling with guns and and torpedoes now plied the coasts day and night.  The enemy submariners also faced a violent storm from the sky if they dared surface for long.  Navy dirigibles and seaplanes scanned thousands of miles of open ocean, and Army Air Corps Liberators, Navy Privateers, and other patrol aircraft would swoop in to strafe the subs if they were caught on the surface.  Diving did not automatically mean deliverance, however, as many of the aircraft were equipped with depth bombs equipped with hydrostatic fuses that were just as deadly as depth charges that the destroyers and cutters carried.

Within the hangar deck of the escort carrier Santee (CVE 29), en route from Hampton Roads to North Africa to take part in Operation Torch in November 1942, squadron ordnancemen check Mark 17 depth bombs that will be used against enemy submarines.  The Mark 17s, which weighed 325 pounds each, contained TNT explosive, but less than a year later, the Mark 47 depth bombs, which were the same size yet 30 pounds heavier and contained the much more powerful Torpex explosive, were being hauled around on the same support equipment. (Lt. Horace Bristol/ Naval History and Heritage Command image) 
Naval Weapons Station Yorktown, across Hampton Roads and up the York River, kept the patrol aircraft well-supplied with these depth bombs.  Their lethality increased when the explosive within the mines was changed from TNT to the more powerful Torpex (derived from "torpedo explosive") after a new loading facility capable of handling the new explosive was established at Yorktown in December 1942.  Each 355-pound depth bomb carried approximately 252 pounds of Torpex.

At about 11:00 am, a truck towing four dollies carrying six of these depth bombs each, enclosed in metal brackets, was on its way from from Pier 2 on the naval operating base and was passing the southeast corner of Chambers Field on the naval air station en route east towards weapons magazines on the far side of the larger East Field (today known as Chambers Field).  Though the exact chain of events is unclear, one of the 24 depth bombs partially slipped from a dolly and began dragging down Tow Way Drive.  A Marine sentry saw the wayward trash can-sized metal canister smoking, ordered the driver to stop, and either the driver or the sentry alerted the nearby fire station.  What is clear is that Assistant Fire Chief Gurney Edwards made a heroic but unsuccessful attempt to head off what would become the worst disaster in NAS Norfolk's long history.

Many of the photographs taken in the hours and days after the accident by photographers from the air station's public relations office were marked "Confidential" and remained under wraps for decades, yet the Hampton Roads Naval Museum now holds over 100 of them, from pictures taken during the firefighting and first response to the investigative phase.

Along with the tragedy of those lives which were lost and possible clues to what might have caused the accident, the photographers also documented the heroic efforts to limit the damage caused by the tremendous explosion, look for and rescue the survivors, and treat the wounded.

In addition to Seaman 2nd Class Elizabeth Korensky, the only female killed in the disaster, there were other WAVES (Women Accepted for Volunteer Emergency Service) probably injured, as well as female civilian employees of the nearby Assembly and Repair Department of the air station, which was also damaged.  Here an unidentified female is assisted into an official vehicle for transport away from the area of the explosion. (Hampton Roads Naval Museum file)
Local delivery trucks were pressed into service to help deliver the wounded away from the accident scene. (Hampton Roads Naval Museum file)

At the damaged NAS Norfolk dispensary roughly 100 yards from the site of the explosion, stretcher bearers await admittance with some of the hundreds wounded in the accident.  many would be rerouted to the new Norfolk Naval Hospital compound established just south of the naval operating base (and today home to Fleet Forces Command), as well as Portsmouth Naval Hospital.

Hurricane Maria Resurrects Ghosts of Wars Past

Although news reports about the devastation wrought by Hurricane Maria, which recently made its closest approach to Hampton Roads, frequently center upon the destructive winds and tidal flooding that such a storm can bring, this week it has come to light that there were other less-recognizable threats unleashed by the storm as it made its approach to North Carolina's Outer Banks.  On Monday, beachgoers found a barnacle-encrusted sea mine near the town of Avon on Cape Hatteras National Seashore, and another one was discovered nearly 80 miles north in Corolla, just south of the Virginia state line.

An object (above) presumed to be a sea mine was found near Avon on Cape Hatteras National Seashore on the morning of September 25, 2017, and another one was found near the town of Corolla about 80 miles north on the Outer Banks of North Carolina that same morning. They were subsequently turned over to military explosive ordnance disposal technicians.  Thankfully, the Corolla mine turned out to be a training target.  (National Park Service)

During the last century, mines have posed some of the gravest enemy threats to shipping in our home waters.  During both World Wars I and II, German submarines deployed mines along the Mid-Atlantic.  It was an effective, albeit unpredictable tactic.  The Naval History and Heritage Command is currently helping lead an effort to survey USS San Diego, which ran afoul of a suspected mine off the eastern end of Long Island on July 18, 1918. We are also approaching the 99th anniversary of the second such incident that took place during the First World War, not far off the eastern seaboard. On September 29, 1918, the battleship Minnesota (BB 22) ran into a mine only 20 miles off the coast of Delaware.

Built at Newport News Shipbuilding and commissioned on March 9, 1907, just in time for the Jamestown Tercentennial Exhibition and the epic circumnavigation of the globe with the Great White Fleet that followed, the veteran of the 1914 Vera Cruz expedition was assigned to Battleship Division 4, mainly to provide practical gunnery and engineering training for the tens of thousands of new recruits the Navy was taking in during World War I.  She was sailing off the Delaware Breakwater when she struck a mine that had been deployed earlier by U-117. 

Miraculously, only three days after striking a mine off Fenwick Island on the Maryland/ Delaware border on September 29, 1918, USS Minnesota (BB 22) was safely ensconced in a dry dock at the Philadelphia Naval Shipyard, where the serious damage that had been inflicted by a to her bow by a German mine could be ascertained.  She would remain there for five months. (Naval History and Heritage Command Photograph) 
Despite sustaining heavy flooding to her bow, there were no casualties and the battleship was able to make it to Philadelphia under her own power.  She would remain at Philadelphia Naval Shipyard for five months, during which time the war ended.  In January 1919, Navy Secretary Josephus Daniels visited the battleship and personally commended 27 crew members for their "courage and efficiency." After leaving Philadelphia, Minnesota would do her part bringing thousands of American soldiers home from Europe.

Douglas MacArthur's celebrated "Rainbow Division" (42nd Infantry Division, U.S. Army National Guard), crowd the decks of USS Minnesota (BB 22) upon their return to New York from France in 1919.

The Minnesota incident of 99 years ago ended happily, but it stands out as the exception and not the rule in the long, violent history of what was originally called the "torpedo" by its inventors during the American Civil War. Although enemy mines did the worst damage to American vessels during both Twentieth Century wars, not to mention in the Middle East during the latter part of the century, it should not be forgotten that American-made mines were also deployed in large numbers along our coasts, particularly during the Second World War.  Although intended to protect American merchant vessels and warships from the enemy submarine threat, they too caused damage to American shipping when merchant vessels strayed off course or their captains and pilots did not possess the latest information.  

While waiting for a harbor pilot to arrive on the "dark and stormy night" of February 16, 1942, the one-year-old, 554 foot-long tanker SS E.H. Blum of the Atlantic Refining Company, described as "one of the largest and finest tankers in the world" in the War Record of the Fifth Naval District, was ripped in two after drifting into a Navy minefield only 950 yards off the Cape Henry lighthouse.  On June 11, the SS F.W. Abrams of the Standard Oil Company "through a combination of unfortunate circumstances which included bad weather, a misconception of escort duties, and lack of proper navigational information, strayed into the Hatteras Mine Field and was eventually lost."  

Just three days later, on June 15, two American ships and one British vessel ran into a German minefield within sight of Virginia Beach that had been set by U-701, killing 17 on the British vessel, HMT Kingston Ceylonite, and one on SS Robert C. Tuttle.

Despite a concerted effort to sweep the area for German mines, SS Santore encountered another of U-701's mines while assembling to leave Hampton Roads in Convoy KS-511 on June 17, listed to port, and quickly sank, taking three crew members with her.  

Before the month was over, the 7,256-ton Norwegian passenger-cargo vessel MV Tamesis became the second ship sunk by the "friendly Hatteras Mine Field."  The American tug Keshena became its third victim on July 19 while attending to the Panamanian-flagged J.A. Mowinckel, that had itself been damaged by torpedoes and mines.  Three were killed in the tug's engine room.

Whether the mines that emerged from the depths off North Carolina this week present a renewed threat from a past war has yet to be ascertained, but one thing is for certain: the story of mines off the East Coast is far from over.

Approaches to Virginia Capes Mined in 1942: What Did the Swiss Know? And When Did They Know It?

Four tugs gently push the tanker Robert S. Tuttle
 after the ship struck a mine off of False Cape. 
The tugs took the tanker to Baltimore for
 repairs. She survived the war.
In June 1942, the Kreigsmarine began to wrap up Operation Paukenschlag,  the U-boat offensive on the American eastern seaboard. As U-boats started to sail east, U-701 left behind a going away present: a minefield near the entrance to the Chesapeake Bay. 

A thirteen ship convoy labeled KN-109 (Key West to Norfolk) steamed into the minefield, shortly after U-701 finished laying the mines. Escorted by the Norfolk-based destroyer USS Bainbridge (DD-246) and the armed fishing trawler HMT Kingston Ceylonite, the convoy switched from a double column formation to a single file formation as it sailed off the coast of False Cape.  Shortly after the switch, one of the tankers in the convoy, SS Robert S. Tuttle, struck a mine on the starboard, forward section of the ship.  Thirty minutes later, Esso Augsta also struck a mine.  During the confusion, Kingston Ceylonite turned to help, only to hit three mines in a row, completely obliterating the trawler. The explosions killed seventeen of her thirty-three man crew.

Thinking a U-boat was in the area, Bainbridge turned to counter-attack and dropped eight depth charges. While there was no submarine the area, the depth charges set off nine mines.  Despite sweeping the area by other ships out of Hampton Roads, the minefield continued to cause further damage well into September.

U.S. Navy intelligence suspected that neutral-flagged, but pro-Axis, merchant vessels were laying mines on behalf of the Germans.  Intelligence officers from the Fifth Naval District (headquartered at Naval Station Norfolk) boarded three ships: the Greek-flagged tanker Helena Kulakunds, the Spanish-flagged freighter Monto Mulhacen, and the Swiss-flagged freighter Calanda.  The officers found no evidence of mines or mine laying equipment.  However, they did find the ships' sailing instructions and noticed they were very different than those of Allied-flagged merchant ships.  Specifically, the instructions informed the ships not to sail in the waters off of Virginia Beach and False Cape.  The officers discovered that the instructions came from the Swiss Embassy in Portugal.

Allied ships, which took them straight into the minefield. The neutral ships, however, followed the
dotted line, which took them north of the minefield.
The Fifth Naval District Intelligence Office concluded that the freighters and the embassy were tipped off by German or Italian officials. It wrote, "It is most unusual, that a neutral nation, supposedly with no first-hand information of the approaches to a belligerent harbor, would undertake to issue routing instructions for the entrance in direct contravention to the instructions issued by nations charged with keeping a channel into such harbor open and free of mines."
