"Second Lieutenant David R. Kingsley, U.S. Army Air Corps, 97th Bombardment Group, 15th Air Force. Place and date: Ploesti Raid, Rumania, 23 June 1944: For conspicuous gallantry and intrepidity in action at the risk of life above and beyond the call of duty, 23 June 1944 near Ploesti, Rumania, while flying as bombardier of a B17 type aircraft. On the bomb run 2d Lt. Kingsley's aircraft was severely damaged by intense flak and forced to drop out of formation but the pilot proceeded over the target and 2d Lt. Kingsley successfully dropped his bombs, causing severe damage to vital installations. The damaged aircraft, forced to lose altitude and to lag behind the formation, was aggressively attacked by 3 ME-109 aircraft, causing more damage to the aircraft and severely wounding the tail gunner in the upper arm. The radio operator and engineer notified 2d Lt. Kingsley that the tail gunner had been wounded and that assistance was needed to check the bleeding. 2d Lt. Kingsley made his way back to the radio room, skilfully applied first aid to the wound, and succeeded in checking the bleeding. The tail gunner's parachute harness and heavy clothes were removed and he was covered with blankets, making him as comfortable as possible. Eight ME-109 aircraft again aggressively attacked 2d Lt. Kingsley's aircraft and the ball turret gunner was wounded by 20mm. shell fragments. He went forward to the radio room to have 2d Lt. Kingsley administer first aid. A few minutes later when the pilot gave the order to prepare to bail out, 2d Lt. Kingsley immediately began to assist the wounded gunners in putting on their parachute harness. In the confusion the tail gunner's harness, believed to have been damaged, could not be located in the bundle of blankets and flying clothes which had been removed from the wounded men. With utter disregard for his own means of escape, 2d Lt. Kingsley unhesitatingly removed his parachute harness and adjusted it to the wounded tail gunner. Due to the extensive damage caused by the accurate and concentrated 20mm. fire by the enemy aircraft the pilot gave the order to bail out, as it appeared that the aircraft would disintegrate at any moment. 2d Lt. Kingsley aided the wounded men in bailing out and when last seen by the crewmembers he was standing on the bomb bay catwalk. The aircraft continued to fly on automatic pilot for a short distance, then crashed and burned. His body was later found in the wreckage. 2d Lt. Kingsley by his gallant heroic action was directly responsible for saving the life of the wounded gunner." (Patrick Holscher)

FINLAND: In Viipuri, the Red Army again tries to continue its offensive. After an artillery preparation starting last evening and lasting through the night, the Soviet troops cross the straits in assault boats and through the ruins of a railway bridge. Eleven Finnish artillery battalions and German Stukas bombard the Soviet troop-concentrations, and those Red Army soldiers able to reach the western bank are soon eliminated by the defenders.

In today's battles west of Viipuri, Lt. Col. Alpo Marttinen's Infantry Regiment 61 (17th Division) especially distinguishes itself repelling the Soviet attempts to advance west from the city. Lt. Col. Marttinen's prowess is recognized by his immediate promotion to full colonel (thus becoming at the age of 35 the youngest full colonel in the Finnish Defence Forces at this time). Later Col. Marttinen is awarded the Mannerheim Cross, 2nd Class.

MARIANAS ISLANDS, SAIPAN: USS Manila comes under Japanese air attack during refuelling operations. Two Japanese fighter bombers attacked from dead ahead, dropping four bombs that exploded wide to port. Intense AA fire suppressed any other attacks but as a precaution, four P-47s were launched as a Combat Air Patrol (CAP) until radar showed no "bogeys." The P-47s then flew to Saipan. USS NATOMA BAY also launches her remaining 12 P-47s.

The IJN begins high-level bombing attacks against USN vessels off Saipan. Between 0000 and 0100 hours, seven "Betty" bombers ( Navy Type 1 Attack Bombers) from Iwo Jima attack; one drops bombs on the wake of a cruiser while the other six damage several vessels.

The USN's Task Groups 58.1, 58.2 and 58.3 is retiring towards Eniwetok Atoll leaving TG 58.4 to support the landings on Saipan. Radio intercepts indicate that the Japanese are concentrating about 100 aircraft on Iwo Jima, Volcano Islands, and TG 58.1 is ordered to change course and attack the island.

US and Japanese forces clash violently at "Death Valley", near Mount Tapotchau.
