After four days, Grayback shook the other sub and continued on patrol.

But after some duct tape and encouragement, the "Grayback" completed a run.

On 12 June, the remaining team members were transferred back to Grayback.

That is Thad Grayback who has a farm up the road.

Grayback had ended her last patrol, one which cost the enemy some 21,594 tons of shipping.

At 2300 hours on 5 June, the men were to be transported back to Grayback by helicopter.

Grayback continued on patrol, torpedoing and damaging several Japanese ships.

He had gone down as skipper of Grayback, after a series of outstanding patrols.

Grayback sent ashore two men, then submerged at dawn to avoid enemy aircraft.

After an unsuccessful attack the following night had exhausted her torpedo supply, Grayback headed home.

Due to reach Midway on 7 March, Grayback did not arrive.

Shortly after midnight the team launched from Grayback but a combination of navigation errors and strong current took them off course.

The Regulus missile program ended in 1964 and Grayback was withdrawn from active service.

However, the destroyer evaded the torpedoes and dropped 19 depth charges on Grayback.

Grayback received eight battle stars for World War II service.

The fifth war patrol began as Grayback sailed from Australia on 7 December 1942.

Then, on 25 December, Grayback surfaced to sink four landing barges with her deck guns.

In a night surface attack Grayback fired a spread of six torpedoes at the seven freighters and their three escorts.

This first attack sunk one freighter and damaged another before 'Grayback' dived to elude depth charges.

Growler and Grayback, with four missiles, or Halibut, with five, could patrol alone.

Grayback: Leader and chieftain of the Wolf Clan.

As night fell, 'Grayback' surfaced offshore and by coded light signals directed the small boat "home safe" with the rescued aviators.

Grayback can refer to:

On 27 August 1963, while snorkeling to recharge batteries, Grayback was buffeted by particularly strong seas.

This Wolf is extremely loyal to Grayback and keeps on calling him "Lord" which he dislikes.

Knot (Calidris canutus)

VAN GILS, JAN A. (2005) Digestive bottleneck affects foraging decisions in red knots Calidris canutus.

Red Knots Calidris canutus and Dunlins Calidris alpina were found in radar studies to fly 5 km per hour faster in flocks than when they were flying alone.

The Red Knot (Calidris canutus) (just Knot in Europe), is a medium sized shorebird which breeds in tundra and the Arctic Cordillera in the far north of Canada, Europe, and Russia.

The DRM went largely unnoticed, but a recent paper by Van Gils describes how red knots Calidris canutus forage based on digestive bottlenecks and confirmed their foraging according to the DRM rather than the CM model of optimal foraging.

RED KNOT Calidris canutus Conservation priority score: 21 Threatened by overharvesting of horseshoe crabs in Delaware Bay; the crabs' lay billions of eggs that provide a food supply that is critically important for the Red Knots' successful migration to arctic breeding grounds.
