June 1945

10th War Patrol of USS Dace. Fourth out of Pearl Harbor after transferring from Fremantle in January 1945 after six highly successful patrols.Assigned area is Area 10- Sea of Japan.

After stopping at Guam for fuel, navigated and plotted the minefields of Tsushima Straits on 8 June 1945(see earlier thread for screenshots). Enter Sea of Japan that night. Morning of June 10th spotted a small fleet of fishing boats and went for battle surface. Several opened fire with light machine guns and auto cannons. 5 inch deck gun crew as well as 40mm and 20mm fire quickly silenced them. Sunk 12 fishing boats. Moved on to open ocean area to interdict traffic between Korea and Japan.

On 11 June made contact with a large troopship of Horai Maru Class escorted by a Matsu Class Destroyer and an Otori Torpedo boat making high speed. Tracked but a pesky patrol plane kept forcing us to dive, eventually spotting us and attacked. Soon an apparent patrol of two DD(Akizuki and Momi) arrived on scene and began screening for the troopship, eventually moving in to hunt us, forcing us to go deep and run silent. They dropped 30 depth charges but none were too close.Once clear, we headed in last known direction of transport as it was now dark, but unable to reestablish contact.

On 13 June off Akita sunk one medium and one small tanker. Small tanker was first hit by a Mark 27 "Cutie" homing torpedo, Mark 16's finished off the other tanker. After the brutal depth charging from six escorts, came to scope depth and found the small tanker dead in the water, prop apparently destroyed by the "Cutie" hit. Surfaced in an attempt to catch up with last tanker but heavy air patrols prevent this. Went out to sea for night time battery charge.

On 14 June was conducting submerged coastal patrol off Nigata. Sunk an Akizuki Destroyer making a high speed run south along the coast.

15 June destroyed 8 fishing boats and sampans.A low flying "Emily" patrol plane dropped a close depth charge, which caused heavy damage to conning tower after a crash dive. Moved out to sea to repair that night.

16 June attacked 2 large merchants with escorts off Tsugaru Strait, sunk both with Mark 18 torpedoes.Prolonged depth charging from the escorts left boat kept us under for 14 hours.

17 June- Destroyed fishing boats, all exploded easily, must have been carrying ammunition.

18 June-Attacked a large Merchant off Nanao Bay. Escorts were top notch and forced a shot from 3900 yards, almost the Mark 18's max range. 2 of four torpdoes hit, leaving vessel crippled. The six escorts were fooled by decoys dropped but kept us down. When cam back to scope depth, merchant was gone, apparently repaired enough to limp away.

19 June- Submerged at dawn and went deep in Toyama Bay. At 0800 made sound contact with multiple ****s. There was a freighter with five escorts, mostly Type C and D. Managed to get to 800 yards off track with perfect shot. Fired last Mark 16's. Both hits, destroying the ship. Escorts soon raced in and dropped many depth charges. Despite decoys and being at 580 feet(at the limit for a gato) they stayed with me. Seas were glassy and calm, ideal sonar conditions. Thought had lost them, but one persistent escort kept coming back every now and then and reestablishing contact. After several hours of this seemed to have escaped again when an escort came close and began pinging away. Dropping a large pattern. Many explosions, none close then suddenly. BAM BAM. Two extremely close explosions. Lights went out, damage reports piled in. The the forward torpedo room was wrecked, flooding, control room and conning tower wrecked with light flooding. Hull damage reported . As tried to climbing away so did not sink to crush depth, suddenly hull collapsed, all was lost.

Sucks losing a career I have been playing for about three months, especially on what was most likely last patrol with end of war so near.

Sad coincidence, during the war, USS Bonefish was lost on June 19, 1945 in Toyoma Bay as well after attacking and sinking a single merchant with five escorts. While I did add this group at this time and location when adding traffic to game a while back, was not aware of it.

Japanese ASW really does get better in SH 4 as war goes on.This, along with more escorts as in real life, made for a tougher experience for US submarines.
