Theblinking of navigation lights indicated the continued use of trickeryto att~act B-29 fire ..

"C . Mission 258. 73r d '.'11M. Salsai I(1) An estimated 10 to 15 enemyaircraft were enco.w.tered

and .5 attacks were su.stained while the B-29's were illuminated bysearchlights or were in the vicinityof' the target. Oneof the F-29'sreceived minor damageas a result of canbined E/A and A/A activity.(2) Evasive action taken ccnsisted of' slight turns and

changes in altitude.(3) 'rIvocrews at 10,800 feet observed the Tokushimaand

(1) A maximum of 10 enemyaircraft were Sighted, all tut1n the target area.(2) Onepossible attack w a s sustained by the B-29's.The enemy aircraft Was believed to be a TIE which fired 2 quick burstsfran 5 o'clock. The attack was so sudden and unexpected that fire WISS

not returned.d. Mission 260 . 314th lling. Girur A . probable 10 to 15 airoraftmade 3 attacks. Most of the enemy aircraft enocuntered were tl3'inSarQlnd in the target area with their lights al. They were reported tobe shooting at randan rather than attacking an individual B-29. Cklecase was reparted at an attack being made en a plane picked up by ssearchlight near Kitagata. &dde~ the searchl18ht held the attackingfighter in its beeun and not the B-29. It was believed by acme at thecrew that the night fighters were attempting to lcoate possible target.visuall.y~ The eneuy fighters passed the B-29's, high. lar or en eitbarside. They also creased the O
