لم يكن شيلدز غرين ممن ينكمش أمام المشقّات أو الأخطار. كان رجلًا قليل الكلام، وكان نُطقه متقطعًا على نحوٍ فريد، غير أن شجاعته واعتزازه بنفسه جعلاه شخصيةً ذات وقار.

“Shields Green was not one to shrink from hardships or dangers. He was a man of few words, and his speech was singularly broken; but his courage and self-respect made him quite a dignified character.”Frederick Douglass — The Life and Times of Frederick Douglass (2012)
