THERE'S going to be an armed invasion by the enemy near Kelty tomorrow (Sunday) and, spoiler alert, we're going to win.

It's nothing to be alarmed about but wartime re-enactments are the name of the game at Lathalmond as Defend Fife returns after a COVID-inflicted ceasefire.

You can also hop on board a World War One train, hide out in an Anderson shelter, experience trench warfare and find out about the Polish sub that set sail from Rosyth but has never been found.

Grant Robertson, a trustee of Shed 47 Railway Restoration Group, said: "The trustees have taken on the Defend Fife event and added the Lathalmond wartime element to it.

"It couldn't run due to COVID in the last two years and now it's back with a smaller afternoon event this Sunday, with a lot of the same re-enactment people involved, and the hope is we'll grow it and turn it into something absolutely huge in the future."

In previous years, there was a parade through the centre of Dunfermline but, while popular, that posed logistical problems and effectively split crowds between two sites three miles apart.

He confirmed: "Sunday's event is purely up at Lathalmond.

"It's a World War Two heritage site, built by the Royal Navy in 1940-41, so we thought it would be ideal from a historical perspective and it has wartime buildings as well."

The Lathalmond Wartime & Defend Fife event aims to bring history to life by transporting you back to wartime Britain.

There will be military encampments, vehicles and weaponry, exhibitions and talks, an "ambush" on the Home Guard and children's activities, while re-enacters have also dug a World War Two trench, the same way our troops had to.

Grant added: "There's a battle re-enactment at 3pm and it's a what-if scenario, if there had been a successful invasion from opposition forces.

"It's 15 minutes long and you'll see them getting repelled by the Allies.

"Afterwards, a trophy will be awarded for the best display in memory of one of the re-enacters, Dean Bowen, who passed away from COVID."

There's also an international flavour as Dunfermline was home for Polish soldiers who were exiled to Scotland and ships from the Polish Navy were based at Rosyth during World War Two.

The consul general of Poland, based in Edinburgh, is due to attend and stories told will include the great war hero, General Stanisław Sosabowski, and the disappearance of one of their submarines.

ORP Orzel arrived at Rosyth Dockyard in October 1939 after escaping internment in Estonia and surviving an arduous journey through the Baltic Sea.

It went on to serve with the Royal Navy on missions in the North Sea, and around the Norwegian coast, but on May 23, 1940, it left Rosyth and was lost at sea with 60 Polish and three British sailors on board.

The sub was never found – it's classed by the Poles as still being "on patrol" – although there are suggestions that work to build windfarms off the Fife coast may yet uncover its final resting place.

The event is on from 11am to 4pm, entry is £5 and it's free for under-16s.

There will be a free vintage bus service to the site, running every hour from Dunfermline bus station.

The bus and railway museums, as well as the narrow gauge train track, will also be open.
