Good morning. Part of the research I have been doing on my grandfather has now come down to finding out more information about the Omaha Beach landing tables. I have tried to understand the terminology, but to no avail. Perhaps someone here can help. On this website, https://www.dday-overlord.com/.../omaha-beach/landing-table , I understand the first wave times, i.e., H Hour was about 6:30, and so forth. The Omaha Beach Second Wave listing on the right of the page, shows Q+00, etc. and Third Wave shows 3T+00, etc. What day and times were those waves? Were those on June 6? My grandfather says in two different written memoirs that he landed on Omaha on D-Day in the second wave (and he said it wasn't much better than the first wave), about 7:30 a.m., and spent the day and night pinned down on the beach. In a third memoir, written later in life, he says something landing on the eve of D-Day (could have meant evening??) and was on the beach all night. He was an artillery officer (forward observer) and landed with the 1st Inf Div. He was part the 186th Field Art Battalion, V Corp Artillery.
