Morison was criticized by some African - American scholars for his treatment of American slavery in early editions of his book " The Growth of the American Republic " , which he co - wrote with Henry Steele Commager and William E . Leuchtenburg . First published in 1930 , the first two editions of the textbook , according to these critics , echoed the thesis of " American Negro Slavery " ( 1918 ) by Ulrich Bonnell Phillips . This view , sometimes called the Phillips school of slavery historiography , was considered an authoritative source on the history of American slavery during the first half of the twentieth century , despite the intense criticism by some African - American scholars for its alleged racist underpinnings . Phillips ' theories were considered by many to be ground - breaking and progressive when first proposed . In 1944 , the NAACP began its criticism of " The Growth of the American Republic " . In 1950 , Morison , while denying any racist intent — he noted his daughter ' s marriage to the son of Joel Elias Spingarn , the former President of the NAACP — reluctantly agreed to most of the demanded changes . Morison refused to eliminate references to slaves who were loyal and devoted to their masters because they were treated well , and to some positive " civilizing " effects of the American system of slavery . Morison also refused to remove references to stereotypes of African Americans that he believed were vital in accurately depicting the racist nature of American culture in the nineteenth and early twentieth centuries — an era when even the most enlightened progressive thinkers routinely explained many aspects of human behavior as being a result of innate racial or ethnic characteristics . In the 1962 edition of the textbook , Morison removed additional content that these critics found offensve . Battle of Savo Island . In his semi - official account of the Battle of Savo Island , a disastrous defeat for the U . S . Navy in World War II , Morison partly blamed the defeat on the failure of an Australian aircrew to inform the Americans of the approaching Japanese forces . Morison appears to have based this story on inaccurate , now refuted , information . Honors and awards . Military , civilian , and foreign honors Honorary degrees Literary prizes Works .
