Twelve ships took off at 10:25 hours this morning to bomb Vigevaro railroad bridge, but they found the objective completely covered by stratus cloud layers and proceeded to the alternate which was Tortona railroad bridge. The formation was over the target at 12:13 hours, dropping their bombs with precision accuracy directly on the objective. The vital bridge was observed to be down after the devastating attack. Other flights in the formation were severely holed by flak, but the 487th escaped the barrage and all planes returned undamaged. |
