The Prince of Wales will travel to the Netherlands to mark the 60th anniversary of the Battle of Arnhem.
Prince Charles will honour those who died in the famous raid
He will take part in a memorial service at the British Military Cemetery, Oosterbeek, on 19 September.
An estimated 1,130 paratroopers were killed and another 6,450 captured during the ill-fated bid to capture Arnhem bridge.
Meanwhile, the prince visited British troops in Germany on Friday who are preparing for duty in Iraq.
Dressed in combat fatigues, he watched as members of the 1st Queen's Dragoon Guards took part in a mock ambush.
The prince saw troops overpower colleagues dressed in Middle Eastern-style headscarves and tunics.
He is colonel-in-chief of the Queen's Dragoon Guards and travelled to Sennelager to meet some of the 400 troops who will travel to Basra next month.
'Bridge too far'
The assault on Arnhem bridge - dubbed the "bridge too far" battle - was part of the largest airborne military operation ever mounted.
Around 10,000 British paratroopers were dropped during Operation Market Garden, an attempt to capture Dutch bridges over the Rhine, while American forces focused on other targets.
But the paratroopers were dropped too far from the bridge and encountered two SS Panzer units which were in the area after a training exercise.
After fierce fighting - immortalised in Lord Attenborough's film A Bridge Too Far - the allies' withdrew from Arnhem nine days later.
The prince, who will also attend a regimental reception, is colonel in chief of the Parachute Regiment.
He has just completed a two-day trip to Northern Ireland.
During his stay, he visited the disused Crumlin Road courthouse and prison in Belfast.
He also attended the opening of the World Ploughing Championship in Ballykelly.
