committed suicide. On 21 April, the final decision to evacuate Empire forces to Crete and Egypt was taken and Wavell – in confirmation of verbal instructions – sent his written orders to Wilson. 5,200 men, mostly from the 5th New Zealand Brigade, were evacuated on the night of 24 April, from Porto Rafti of East Attica, while the 4th New Zealand Brigade remained to block the narrow road to Athens, dubbed the 24 Hour Pass by the New Zealanders. On 25 April (Anzac Day), the few RAF squadrons left Greece (D'Albiac established his headquarters in Heraklion, Crete) and some 10,200 Australian troops evacuated from Nafplio and Megara. 2,000 more men had to wait until 27 April, because Ulster Prince ran aground in shallow waters close to Nafplio. Because of this event, the Germans realised that the evacuation was also taking place from the ports of the eastern Peloponnese. On 25 April the Germans staged an airborne operation to seize the bridges over the Corinth Canal, with the double aim of cutting off the British line of retreat and securing their own way across the isthmus. The attack met with initial success, until a stray British shell destroyed the bridge. The 1st SS Motorised Infantry Regiment (named LSSAH), assembled at Ioannina, thrust along the western foothills of the Pindus Mountains via Arta to Missolonghi and crossed over to the Peloponnese at Patras in an effort to gain access to the isthmus from the west. Upon their arrival at 17:30 on 27 April, the SS forces learned that the paratroops had already been relieved by Army units advancing from Athens. The Dutch troop ship was part of a convoy evacuating about 3,000 British, Australian and New Zealand troops from Nafplio in the Peloponnese. As the convoy headed south in the Argolic Gulf on the morning of 27 April, it was attacked by a Staffel of nine Junkers Ju 87s of Sturzkampfgeschwader 77, damaging Slamat and setting her on fire. The destroyer rescued about 600 survivors and came to her aid, but as the two destroyers headed for Souda Bay in Crete another Ju 87 attack sank them both. The total number of deaths from the three sinkings was almost 1,000. Only 27 crew from Wryneck, 20 crew from Diamond, 11 crew and eight evacuated soldiers from Slamat survived.
