"Six Hurricane aircraft have arrived in Malta to join the Fighter Flight. Early this afternoon two Hurricanes landed from Bizerta after a difficult journey across southern France and along the North African coast. As dusk fell, two more completed the same journey, followed by two more in the early evening.
The six aircraft were all that reached Malta out of twelve Hurricanes and twelve Blenheims that set off from the UK on 18 June. They join recently arrived Hurricanes from Egypt and will significantly strengthen the Island’s defences"
