[1][7] After partisans belonging to the Eighth Garibaldi Brigade ambushed troops approaching the hamlet,[1] fourteen soldiers of the Sturmbattaillon OB Sudwest conducted house-to-house searches and summarily killed civilians.

[1][11] In 2013, a trial in absentia acquitted the only two surviving German soldiers, who had been charged with multiple homicide aggravated by trivial reasons.

[8][9] On 2 April 1944, five detachments of the Eighth Garibaldi Brigade, who were partisans aligned with the Italian Communist Party, occupied Sant'Agata Feltria.

[1] With supporting Italian fascist forces, a German detachment was sent to round up partisans in the area between Monte Fumaiolo and Casteldelci.

[8][9] On 6 April,[7] troops belonging to the Sturmbattaillon OB Sudwest of the 356th Infantry Division passed through Capanne di Verghereto [it].

[1][12] In the morning, they decided to engage the German troops approaching the hamlet, thereby delaying their advance and allowing other companies time to escape.

[1] Arriving in Fragheto at 17:30 that afternoon,[12][13] fourteen soldiers of the Sturmbattaillon OB Sudwest raided the hamlet, conducting house-to-house searches and summarily killing civilians inside.

[1][10] After spending the night of 7–8 April at the confluence of the Senatello and Marecchia,[12][10] a soldier of the Venezia-Giulia Battalion of the National Republican Guard executed the prisoners using a machine gun.

[11] On 10 March 1950, Perugia's Court of Assizes suspended the prosecution of three Italians suspected of having collaborated in the massacre "because the crimes have been extinguished by virtue of amnesty".

[10] In 2006, following the identification of German soldiers involved in the massacres by Interpol,[11] the military prosecutor's office of La Spezia reopened the case.

[12] Some local opinion placed responsibility for the massacre on the partisans, accusing them of attempting an impossible ambush and leaving the hamlet open to reprisals.

[1][10] By presidential decree, on 9 April 2003,[20] the municipality of Casteldelci was awarded the Silver Medal for Civil Valour (Medaglia d’argento al merito civile),[2] with the motivation:[1][20] A small town, during the last world war, having provided temporary hospitality to a group of partisans, was subjected to a ferocious and blind reprisal by German troops, who massacred thirty of its citizens, mostly elderly people, women and children, and destroyed the entire town.The Fragheto massacre inspired the foundation of two local civic associations: Casa Fragheto in Fragheto in 2000 and Il Borgo della Pace in Novafeltria in 2003.

[1] In 2017, Il Borgo della Pace sponsored a short film by Roberta Corsi and Fabio Imola that retold the story of the massacre.
