A green flare will be set off to signal the start of tonight's display and mark the moment 100 years ago the town's lifeboat crew completed a daring double rescue.

It is regarded as one of the most famous week's in Cromer's history.

On January 9, 1917, the town's lifeboat took part in a daring double rescue which would save the lives of 33 people.

Legendary life boatman Henry Blogg led a crew of 40 volunteers to the aid of the Greek steam ship the Pyrin. Later that night they were called to help a second crew, this time on the Swedish ship the Fernebo which had struck a German mine.

Shortly after midnight, a green flare lit the sky to signal the end of the rescue, and a crowd of more around 5000 who watched from the shore broke into spontaneous applause.

A green flare will be set off from the pier to signal the start of the rescheduled New Year's Day fireworks display in Cromer tonight (Sunday). And it is hoped the 10,000 onlookers anticipated to line the shore this weekend will join in the applause to recreate that memorable moment 100 years ago.

Blogg, who served 58 years on Cromer's lifeboats and went on to become the most decorated lifeboatman in RNLI history, was awarded the first of his three gold medals for his leadership in the rescue. The deputy Coxswain received a silver medal and 12 other crew received bronze awards.

A spokesperson for the display said: 'On the eve of the 100th anniversary of the rescue a green firework will open the 2017 Cromer firework display to mark the green flare which was lit when the Cromer lifeboat reached the Fernebo in 1917.

'At 4.55pm on the public address there will be a short account of the Pyrin and Fernebo rescues, followed by a green rocket, just as a green rocket marked the end of that tumultuous day. We'd like everyone to join the applause, just as 5,000 did on the clifftops a century ago.'

This morning (Sunday), shortly after 10am. Cromer lifeboat will lay a wreath in memory of Private John Sharp, who died as a result of his exertions in the Fernebo rescue and Chief Engineer Johan Anderson, lost from the ship.

They were very busy during World War One because more boats were using the seas around Britain often with hostile motives.

Cromer's New Year's Day fireworks display has been rescheduled for Sunday, Jaunary 8. They will be set off from the town's pier at 5pm. However, motorists are being advised to arrive early to get parked.
