The text on the marker is in Italian and reads:

ROBERT THOMSON**
ventitreenne
tenente pilota americano
messaggero
di libertà e di pace
disceso dal cielo
su questa terra amica
e qui spirò
il 20 aprile 1945
---
pieve di trebbio
con amore di madre
ne raccolse
le spoglie mortali
e ne volle eternato
il ricordo
su questo marmo
25 aprile 1946

his mortal remains
and sought to immortalize
his memory
