---------------------------------------------------------------------------------------------------------

Results:  Target were islands on which Jap bivouac areas and gardens were known to exist through POW intelligence.  No specific aiming points on islands were assigned.  Serious damage is assumed to have resulted in all cases where bomb, shell, rocket, incendiary cluster, and .50 cal. strafing hit the target area.  Nature of targets and weather prevented accurate damage assessment.  One incendiary cluster failed to ignite.

Four PBJ's of this squadron and three F4U's of VMB 155 took off from Majuro at 1216M. 28 July, 1945 for a harassing strike on Jap gardens and living areas on various islands of Wotje Atoll.  The planes proceeded to Wotje with the corasirs flying formation on the mitchells.  Individual targets were assigned each plane and upon arriving over the atoll the formation broke up and each plane proceeded to attack its own targets.  Runs were made in both directions across the line of islands in a direction approximately 90 to the line of the reef.  The Mitchells made their attacks in a shallow glide at 200 knots releases of bombs, rockets, and shells being made from 800' to 1500'.  The Corsairs dropped the incendiary clusters in level flight from an altitude of 75' at 240 knots air speed.  All planes strafed all target areas expending a total of 6800 rounds of .50 cal ammunition.  There was a solid overcast at 2000' with 6/10 scattered clouds below it all the way down to the deck.  The weather was entirely closed in at the NE tip of the Atoll and planes assigned to those targets were forced to attack islands further south.  All runs were rendered more difficult by poor visibility.  Light, meager, inaccurate AA fire was observed from Ormed and Egamedio islands.  One PBJ experienced a hydraulic failure over the target which permitted the nose wheel and one main landing gear to extend.  The emergency hydraulic system proved ineffective to extend the other main gear or to retract the wheels already extended.  The plane returned to base with the other planes in formation and after trying various maneuvers in the air succeeded in getting all gears down and locked and a safe landing was made at 1600M.  The other six planes landed safely at 1530M.

MAINTENANCE

Two PBJ's experienced hydraulic failures, one caused by a cracked sleeve on main landing gear line, the other by a broken line to the bomb door actuating cylinder.

Two PBJ's upon examination showed signs that the bombs had dropped on the bomb bay doors.  If the electrical system is functioning properly in the plane such a thing is impossible, however the systems checks out satisfactorily and the nature and cause of the failure is unknown at present.

Seven out of eight sets of rocket launching posts on one PBJ were partially destroyed when the rockets were fired, cause unknown at present.

All other materiel functioned satisfactorily.
