Day 606 April 28, 1941
Greece. During the day, German bombing sinks Greek torpedo boat Kyzikos and 2 steamers. Overnight, 4170 Allied troops are evacuated from the Peloponnese peninsula. 2 German companies (5th Panzer Division) drive into the port of Kalamata and capture the quay as the evacuation begins. Royal Navy warships sail back to sea, having embarked only 322 men. Most Allied troops are too exhausted to resist but there are several independent small group actions. Sergeant Jack Hinton of 2nd New Zealand Division wins the Victoria Cross for leading an attack to retake the quay, clearing out 3 machine-gun nests and a mortar with grenades and capturing a 6 inch gun. He is shot in the stomach and taken prisoner (he will receive his medal from King George at Buckingham Palace on May 11 1945, after his release). Allied forces recapture the quay (41 Germans killed, 60 wounded, 100 taken prisoner) but it is too late, the warships are gone.
General von Paulus (German Deputy Chief of Staff), who arrived yesterday, orders Rommel to delay his planned attack on Tobruk, reflecting concerns that Rommel is being too reckless. From 6 AM, Luftwaffe bombs Tobruk harbour and defensive positions, to cover the continued buildup of German and Italian troops and armour around the perimeter.
150 miles South of Iceland, U-123 sights convoy HX121 and calls in 5 other submarines. At 4.15 PM, U-552 sinks a tanker, then at 7.25 PM U-96 sinks 2 tankers and a freighter (most crewmen rescued by British rescue ship Zaafaran). U-552 and U-96 are both depth charged by the convoy escorts. U-65 is sunk by depth charges from the British destroyer HMS Douglas (all 50 hands lost).
In the Arabian Sea 1200 miles East of Mogadishu, Somaliland, German armed merchant cruiser Pinguin shells British SS Clan Buchanan (carrying military equipment from USA) from 5 km. Radio signals reporting the attack are sent before the crew of 110 are taken prisoner and is Clan Buchanan scuttled. Royal Navy ships respond to the signals and set out to hunt for Pinguin.

British minesweeping trawler HMT Caroline sinks on a mine off Milford Haven, Wales (the Dutch crew are all lost).
Overnight, Malta is heavily bombed. Destroyer HMS Encounter is badly damaged in drydock by a bomb penetrating her deck and minesweeper HMS Fermoy is destroyed.
This is an argument that some historians such as Keegan have also used in order to prove that Greek resistance may have been a turning point in World War II. According to the film-maker and friend of Adolf Hitler Leni Riefenstahl, Hitler said that "if the Italians hadn't attacked Greece and needed our help, the war would have taken a different course. We could have anticipated the Russian cold by weeks and conquered Leningrad and Moscow. There would have been no Stalingrad".
Despite his reservations, Brooke seems also to have conceded that the start of the offensive against the Soviet Union was in fact delayed because of the Balkan Campaign. John N. Bradley and Thomas B. Buell conclude that "although no single segment of the Balkan campaign forced the Germans to delay Barbarossa, obviously the entire campaign did prompt them to wait."
On the other hand, Richter calls Eden's arguments a "falsification of history". Basil Liddell Hart and de Guingand asserted that, even if Operation Marita delayed the Axis invasion of the Soviet Union, this was not enough to vindicate the decision of the British government, because this was not its initial strategic goal. In 1952, the Historical Branch of the UK Cabinet Office concluded that the Balkan Campaign had no influence on the launching of Operation Barbarossa. According to Robert Kirchubel, "the main causes for deferring Barbarossa's start from 15 May 15-22 June were incomplete logistical arrangements, and an unusually wet winter that kept rivers at full flood until late spring."
However, the Balkan campaign involved a lot of mileage for German motor transport and tanks. Kleist's 1st Panzer Group, the cutting edge of Army Group South, would begin Barbarossa with nearly a third of its tanks at workshops in Germany.
