"
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. Prior to the war, it was called
Sealark Channel. Every year on the battle's anniversary, a US ship in the area 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.
