<P> "Ironbottom Sound" (alternatively Iron Bottom Sound or Ironbottomed Sound or Iron Bottom Bay) is the name given by Allied sailors to Savo Sound, the stretch of water at the southern end of The Slot between Guadalcanal, Savo Island, and Florida Island of the Solomon Islands, because of the dozens of ships and planes that sank there during the Battle of Guadalcanal in 1942--43 . Before the war, it was called Sealark Channel . Every year on the battle's anniversary, a U.S. ship cruises into the waters and drops a wreath to commemorate those who lost their lives . For many Navy sailors, and those who served in the area during that time, the waters in this area are considered sacred, and strict silence is observed as ships cruise through . </P> <Ul> <Li> Battle of Savo Island, 9 August 1942 </Li> <Li> Battle of Cape Esperance, 11--12 October 1942 </Li> <Li> Naval Battle of Guadalcanal, 13--15 November 1942 </Li> <Li> Battle of Tassafaronga, 30 November 1942 </Li> <Li> Operation I - Go, 1--16 April 1943 </Li> </Ul>
