Rusconi testified that at least ten thousand U.S. and Philippine soldiers died during the march. They died from starvation, dehydration, exhaustion, sunstroke, and executions by bullets, beatings, bayonetings, and beheadings. Those who survived were packed into wretched death camps where survival was even more challenging than it had been on the death march. The officers attempted to organize various ways to record the names of the dead, and during the late spring and early summer of 1942 lists of casualties began to filter into Rusconi’s office in Manila. On May 19 the family of Pete Banning was officially notified that he had been captured, was missing, and was presumed dead.
