Joseph Balkoski, in his book Omaha Beach: D-Day June 6, 1944, gives an estimate of about 4,700 total American casualties on Omaha Beach. He arrived at this figure by examining after-action reports, morning reports, and battle narratives for each unit involved at Omaha Beach, and his estimates are regarded as some of the most accurate yet collected. The German 352nd Infantry Division, which had units defending the beach area, suffered about 1,200 casualties.
