Tour 11/17/2008, USS Ahrens (DE-575)
The father of one of the visitors in the second tour group served as a ship's baker on the USS Ahrens (DE-575) in WWII. The USS Ahrens was a member of Destroyer Escort Division 60. One of the big roles that DEs performed was to rescue sailors from stricken ships. The USS Ahrens performed this task on two arduous occasions. The first involved the USS Block Island (CVE-21). And the second involved a collision between a gasoline tanker and a liberty ship in a North Atlantic convoy.
The USS Block Island (CVE-21) was an escort carrier. In 1944, the Block Island, along with four Destroyer Escorts (including the Ahrens) formed a Hunter-Killer Team (TU 22.11). Hunter-Killer teams would actively search an area for U-Boats. Radio Activity and decoded U-Boat messages (from Bletchley Park) would direct the Hunter Killer team to a region. Since a U-Boat would spend most of the time on the surface, patrol planes from the small carrier would narrow the search. Once a U-Boat was found a pair of Destroyer Escorts would be dispatched to finish the U-Boat. Two DEs would continue to escort the Carrier.
In response to the Hunter-Killer Groups, in 1944 the German U-boat command started to arm U-Boats with Acoustic Homing Torpedoes. They also implemented an offensive strategy to sink the escorts: "......Offense is the best defense...... If the enemy bears down on you, do not blind yourselves by going to great depths, but in the daytime remain at periscope depth and fire. You still have enough time after firing to dive. The same applies at night, first fire, then dive. Offense is the best defense. Act accordingly...... "
On May 29, 1944 the USS Block Island was torpedoed by three torpedoes from U-549. The USS Ahrens and the USS Robert I. Paine (DE 578) assisted the USS Block Island. Two other Destroyer Escorts in the group, the USS Barr (DE-576) and the USS Eugene E. Elmore (DE-686) attacked the U-549. The U-Boat was equipped with the newly developed Acoustic Homing Torpedoes, and managed to cripple the USS Barr. The Ahrens and the Paine were stationary during the rescue, and they would have been an excellent targets. It was probably a race, would the Elmore get U-549 before another DE was hit. This survivor's account details the action: ".....At 2040 Captain Hughes ordered all hands to “Abandon Ship”. By 2100 most men went over the starboard side, either jumping or sliding down knotted 40-ft. Rope ladders. As the ship sank the planes spotted on deck slid into the sea like toys, the TBM’s depth changes exploding deep under the surface. Block Island took her final plunge at 2155. We were equipped with various types of life belts / jackets as well as cork supported rope nets. ........... The USS Ahrens DE 575 stopped engines and drifted to a stop in the Atlantic swells, recovering the Block Islanders from the sea. With Ahrens’ engines now stilled, her sonar almost immediately detected U-549. Ahrens skipper radioed the USS Elmore DE 686 coaching the sister ship to where the German submarine lay. Three projectiles from Elmore’s hedgehogs slammed into the U-549’s hull at 2127. A great, grinding internal explosion audible to the monitoring ships destroyed the U-boat a moment later.
A postscript to this story - it appears that the Ahrens was being stalked by U-549. An Ahrens crew member, Maury Gamache was given credit for spotting U-549. Perhaps his sharp eye saved DE-549 (and many of the Block Island survivors): ".....I normally was assigned to the depth charge and K gun area but while we were picking up survivors I was sent to the 101 gun mount, along with an ensign. While I was there he told me to keep a close look out to the opposite side where the survivor activity was taking place, which I did with an occasional look in that direction. After a while, I think it was just after dusk, I saw a periscope on the left side of the ship and I was so speechless that I tapped him on the shoulder and pointed and he saw the same periscope. He immediately notified the bridge and that is when the Ahrens had to break off the picking up of survivors and make emergency speed to avoid being sunk also. ...."
The Ahrens was credited with rescuing 673 sailors from the USS Block Island. The small Destroyer Escort, with it's own crew of 213, had 886 sailors on-board. About a month ago the Slater hosted an open house and had several thousand visitors, but I doubt that 886 were aboard an any given time. I'm pretty sure that a ships baker had his hads full feeding this many sailors. The account from rescued Block Island sailors continues: ".......The next morning, 30 May, Elmore with the damaged Barr under tow, and the two DE’s laden with the CVE survivors, cleared the area for Casablanca, arriving 1 June. The personnel of the two DE’s, did a commendable job of making all hands as comfortable as possible, some giving up bunks for others to catch a few winks. The task of feeding this large number, aboard the Ahrens and the Paine, was without parallel. While we were lined up on the main deck, waiting turns to go below to eat our two meals. Sometimes, from the bridge came the order for some men to shift from one side or to the other to maintain an even keel. The odor of diesel fuel oil was everywhere that we touched. My what a mess! However, we were SAFE. ....."
- Complete Damage Control Reports on the USS Block Island are available.
- Lewis Andrew, in his book Tempest, Fire and Foe, has a detailed account on the USS Ahrens & USS Block Island is detailed on Page 71.
- One Block Island survivor has made large scale models of the USS Ahrens and the USS Block Island which are on display in Latonia, Kentucky.
When ships are packed into convoys of 50 plus ships accidents are bound to happen. The worst ones occur when one of the ships is carrying a highly explosive cargo. On the 13th of October, 1944 the Liberty Ship Howard Gibson and the British gasoline tanker George W. McKnight collided. The USS Holton (DE-703), USS Cronin (DE-704), and the USS Ahrens (DE-575) were involved with the rescue. Once again, Lewis Andrew's excellent book, Tempest, Fire and Foe gives an excellent account on page 58.
This will be my last duty weekend until April 2008. In early December the USS Slater will move to the east bank of the Hudson River to protect the ship from winter ice. It will be closed for tours until she returns to the Albany-side in April. During the winter I'll continue to post to the blog. If anyone has a topic request concerning Destroyer Escorts e-mail me.

Tour 11/11/2007, Depth Charge Magazine

For a good general description of Depth Charge patterns check out:
Historic Navy Ship Association
Gene Slover's Fire Control Page
(1) Details on math - The magazine is 24' x 10' by approx. 5' high. (2,073,600 cubic inches). A Mk. 6 charge is 17" x 28" (6,370 cubic inches). Using those numbers, the magazine could mathematically hold 325 charges.

Tour 11/03/2007, Magazines & Jacks

On one of the tours I was asked about ammunition magazines, and how many 3" rounds the USS Slater held (it's approximately 750 3" rounds). For safety reasons a Destroyer Escort's magazines are on the lowest deck. The USS Slater has a virtual tour that includes a layout of all ship compartments. The 2nd Platform layout details the magazines (they're are detailed in red). A magazine is basically a small, unvented room with storage racks and a heavy duty sprinkler system. There's also a thermometer. At least once a day a gunner's mate will visit every magazine and ammunition ready storage space and log temperature readings. Sparking is a danger. Electric bulbs are sealed in a special globes. When I worked in magazines, I used a special set of tools that were made of a non-sparking copper alloy.

Magazine safety is a big issue. After WWII one Destroyer Escort, the USS Solar DE-221,was destroyed by an accidental magazine explosion.

On another tour I was asked about the little flag on the front (called the bow) of the USS Slater. This little flag is called a Jack, and it flies from a staff (called a jack staff). I was specifically asked, if it was a modern Jack, or a WWII era Jack? The correct answer is that the Slater's Jack is WWII Era (one with 48 stars). In the recent edition of Slater Signals, Tim Rizzuto (Executive Director) goes into detail about obtaining WWII era flags and Jacks for the USS Slater.

Tour 10/27/2007, Hospital Corpsman
Because of the rain I kept the tour below decks (indoor) as much as possible. And, I tried to focus on hospital corpsman related items. During the course of the tour we encountered an uniform with a 1st class rating badge with a red Geneva Cross instead of the Winged Caduceus (which is used today). In 1948, the Navy changed the names and insignia of the Hospital Corps. They also changed the rating name from Pharmacist Mate to Hospital Corpsman.
I know that the Navy places VERY BIG emphasis on technical competence. I did a little research relative to the technical knowledge required for a Corpsman. Here's a few links:
Hospital Corpsman Basic Training Course
www.hospitalcorpsman.org/ (check drop down boxes on top of page for links to reference materials)
Integrated Publishing - Corpsman Manuals
While it isn't included on a regular tour I made it a point to visit the USS Slater sick bay. Since it's off the guided tour I didn't have any good historical background material. A little Google search afterward found this interesting story by the USS Slater's Museum curator, Pat Perrella. It concerns the USS Atherton (DE-169), a Destroyer Escort that had the distinction of sinking the last U Boat during WWII (U-853).
".......Ironically, while U-853 was under deadly attack, with ATHERTON rocking amidst the tremendous noise and force of the exploding ordnance, a life-saving drama was taking place below deck in ATHERTON’S “Sick Bay” and photographs bear witness to the unprecedented event. A German POW was being tenderly attended by Jewish Lt. Maurice Vitsky (Dr.) USN, Surgery, following an emergency appendectomy. Pvt.1/c Franz Krones, German Army POW #31G668894, had been transferred by breeches buoy to ATHERTON from M/V 2-1 on 20 April 1945, while the convoy (GUS-84) was forming near Gibraltar in the Mediterranean. Krones was critically ill with a ruptured appendix and Dr. Vitsky, as Division Medical Officer aboard ATHERTON, operated immediately with the assistance of 20-year-old Pharmacist’s Mate 3rd Class, Thomas J. Ciaccio. The prisoner was helpless and desperately ill. Dr. Vitsky and Phm. Ciaccio compassionately nursed their patient throughout the Atlantic voyage and U-853 attack to drain his infection, administer penicillin and provide whatever nourishment he could sustain. Capt. Iselin was also concerned for his charge and frequently took time to inquire about the status of the patient. The ATHERTON crew never forgot Krones and always wondered about his fate after he was transferred to a military hospital when DE-169 finally reached Boston. ...."
