Divers worked to tunnel under "O-5"s bow so lifting cables could be attached. "Ajax" arrived about midnight, and by early morning, the cable tunnel had been dug, the cable run, and a lift was attempted. Sheppard J. Shreaves, supervisor of the Panama Canal's salvage crew and himself a qualified diver, had been working continuously throughout the night to dig the tunnel, snake the cable under the submarine, and hook it to "Ajax’s" hoist. Now the lift began. As the crane took a strain, the lift cables broke. Shreaves and his crew worked another cable set under the bow and again "Ajax" pulled. Again, the cable broke. All through the day, the men worked. Shreaves had been in his diving suit nearly 24 hours. As noon on the 29th approached, the crane was ready for another lift, this time with buoyancy being added by blowing water out of the flooded Engine Room. Then, just after noontime, the bow of "O-5" broke the surface. Men from the salvage force quickly opened the torpedo room hatch, and Breault and Brown emerged into the fresh air.
