The Mattapoisett Memorial Day parade on Monday will feature its first-ever riderless horse known as a “caparisoned horse,” a historic tradition that honors warriors and highly esteemed soldiers and individuals during a funeral procession. Led by her owner, Cheryl Randall Mach, ‘Honey’ will be formally dressed with two boots belonging to Mach’s grandfather, a WWI cavalry veteran, mounted in the stirrups facing backwards along with a silver cavalry sword.
