Less well-known campaigns were waged by Allied forces in the Mediterranean and Pacific theatersneither of them deliberately planned as a tonnage war in the way that German U-boat campaign was, but both having that effect— and both were also very successful. Although the primary venue for the campaign was the North AtlanticHitler sent U-boats and surface raiders to all corners of the globe in search of the most efficient way to sink the maximum number of ships at minimum cost.

The U-boats campaign was very successful especially in the two "happy periods", of and ofand was able to reduce the total shipping available to the Allies almost to a breaking point inwhen the tide of war started turning against Germany.
On the other side, an important factor in the British anti-submarine effort was the success of the codebreakers at Bletchley Park in reading U-boat messages encrypted using the German Enigma machine.
It is maintained by some historians[ who? Others, including Blair  and Alan Levin, disagree; Levin states this is "a misperception", and that "it Najlepsza codzienna strategia systemu handlu doubtful they ever came close" to achieving this.
In particular, this was because most of the ships sunk by U-boat were not in convoys, but sailing alone, or having become separated from convoys.
Simons in was a recipient of the Oswald Veblen Prize of the American Mathematical Society, which is geometry's highest honor. Staff attribute the breadth of data on events peripheral to financial and economic phenomena that Renaissance takes into account, and the firm's ability to manipulate large amounts of data by deploying scalable technological architectures for computation and execution.
At no time during the campaign were supply lines to Britain interrupted; even during the Bismarck crisisconvoys sailed as usual, although with heavier escorts. Despite their efforts, the Axis powers were unable to prevent the build-up of Allied invasion forces for the liberation of Europe.
In Novemberat the height of the Atlantic campaign, the US Navy escorted the Operation Torch invasion fleet 3, mi 4, km across the Atlantic without hindrance, or even being detected, in what may be the ultimate example of the Allied practise of evasive routing.
In and the Allies transported some 3 million American and Allied servicemen across the Atlantic without significant loss. Unlike the AlliesGermany was never able to mount a comprehensive blockade of Britain.

Nor were they able to focus their effort by targeting the most valuable cargoes, the eastbound traffic carrying war materiel. Instead they were reduced to the slow attrition of a tonnage war.

To win this, the U-boat arm had to sinkGRT per month in order to overwhelm Britain's shipbuilding capacity and reduce its merchant marine strength. In only four out of the first 27 months of the war did Germany achieve this target, while after Decemberwhen Britain R Strategia handlu lamacza joined R Strategia handlu lamacza the US merchant marine and ship yards the target effectively doubled.
As a result, the Axis needed to sinkGRT per month; as the massive expansion of the US shipbuilding industry took effect this target increased still further. Theton target was achieved in only one month, Novemberwhile after May average sinkings dropped to less than one tenth of that figure. By the end of the war, although the U-boat arm had sunk 6, ships totalling 21 million GRT, the Allies had built over 38 million tons of new shipping. Blair attributes the distortion to "propagandists" who "glorified and exaggerated the successes of German submariners", while he believes Allied writers "had their own reasons for exaggerating the peril".
It is this which led to Churchill's concerns. These were R Strategia handlu lamacza threat assessments ", Blair concludes: "At no time did the German U-boat force ever come close to winning the Battle of the Atlantic or bringing on the collapse of Great Britain".
British submarines based in Malta and the aircraft of several Allied air forces, in conjunction with British and Commonwealth surface ships, reduced shipments of essential military supplies such as oil to Axis forces under German Field Marshal Rommel to the point where the Germans there were unable to fight effectively.
By the close of the campaign, Italy had very few merchant ships left. There was another tonnage war in the Mediterraneanas Gibraltar convoys battled against Axis submarines and aircraft to deliver supplies and equipment to Malta, which was under siege by air and sea.

The deliveries enabled Malta to resist persistent air attacks and take the offensive against Axis convoys. Pacific[ edit ] In the early years of the Pacific Warthe submarines of the US Navy were allocated a great variety of tasks and were unable to achieve many of them effectively, particularly given major technical problems with the Mark 14 torpedoes early in the war as well as lack of aggression on the part of US submarine crews.
Despite an awareness that shipping was vital, the Japanese military seriously underestimated the eventual threat from Allied submarines. R Strategia handlu lamacza overconfidence was reinforced by the ineffectiveness of the early activities of Allied submarines in the Pacific War.
The Japanese had impressive night fighting capabilities and heavy torpedo loadouts, but had deficiencies in sonar and radar compared to other navies.
This too, R Strategia handlu lamacza a tonnage war, with rapidly increasing results, and by mid to late Allied submarines and aircraft were experiencing difficulty in finding targets large enough to be worth a torpedo.

Compared to destroyers, merchantman were much more economical in fuel usage while having the capacity to carry full loads of troops plus sufficient equipment and supplies.
