Groves later recalled: During the first week that I was on duty there, I could not walk out of my office down the corridor to Hartman's office without being literally assailed by the officers or civilian engineers with liaison responsibility for various camps.
Groves erindrede senere: I løbet af den første uge hvor jeg gjorde tjeneste der, kunne jeg ikke gå ud af mit kontor og ned ad korridoren til Hartmans kontor uden at blive belejret af officerer og civile ingeniører, der var ansvarlige for forbindelsen til forskellige lejre.
