which raf base did the dambusters fly from
No. 617 Squadron RAF No. 617 Squadron was a Royal Air Force aircraft squadron based at RAF Lossiemouth in Scotland. It is commonly known as the "Dambusters", for its actions during Operation Chastise against German dams during the Second World War. In the early 21st century it operated the Tornado GR4 in the ground attack and reconnaissance role until being disbanded in the Spring of 2014. As of 2016[update] it is in the process of forming ahead of standing up in January 2018 as the first British frontline squadron with the F-35 Lightning II.
Siege of Vicksburg Grant wanted to overwhelm the Confederates before they could fully organize their defenses and ordered an immediate assault against Stockade Redan for May 19. Troops from Sherman's corps had a difficult time approaching the position under rifle and artillery fire from the 36th Mississippi Infantry, Brig. Gen. Louis Hébert's brigade—they had to negotiate a steep ravine protected by abatis and cross a 6-foot-deep (1.8 m), 8-foot-wide (2.4 m) ditch before attacking the 17-foot-high (5.2 m) walls of the redan. This first attempt was easily repulsed. Grant ordered an artillery bombardment to soften the defenses and at about 2 p.m., Sherman's division under Maj. Gen. Francis P. Blair tried again, but only a small number of men were able to advance even as far as the ditch below the redan. The assault collapsed in a melee of rifle fire and hand grenades lobbing back and forth.[11]
