One of the more notable memorials in St. John's is a simple marker for Adelaide Wentworth Waldron, wife of Lt. Comdr. John C. Waldron. Adelaide Wentworth was a daughter of George Wentworth and a cousin of T. T. Wentworth, Jr. for whom the State Museum in old City Hall is named. While the marker was placed at the grave of Adelaide in the Wentworth plot, it also bears the inscription:

"In Memorium LCDR John C. Waldron - Killed Battle of Midway June 4, 1942"

John Waldron was commanding officer of Torpedo Squadron 8 which the lost the entire squadron of 15 TBD's at the Battle of Midway on June 4, 1942. Although his body was not recovered, the family chose this spot to honor his memory.

As reported in Captain M. A. Mitscher's report to the Commander in Chief, U. S. Pacific Fleet on June 13, 1942: "Torpedo 8 led by Lieutenant Commander John C. Waldron was lost in its entirety. This squadron flew at 100 knots below the clouds while the remainder of the group flew at 110 knots, climbing to 19,000 feet. Lieutenant Commander Waldron, a highly aggressive officer, leading a well trained squadron, found his target and attacked.... This squadron is deserving of the highest honors for finding the enemy, pressing home the attack, without fighter protection and without diverting dive bomber attacks to draw the enemy fire. Ensign G. H. Gay, A-V (N), U. S. N. R. is worthy of additional praise for making a torpedo hit and for the presence of mind he showed in hiding under his seat cushion, after being shot down, for several hours, thereby probably saving his own life and giving us an excellent eye-witness picture of the damage caused by the attack on the enemy carriers".

Captain Mitscher later added in his report the following , making reference to recommended awards: "In particular, the Commanding Officer feels that the conduct of Torpedo Squadron Eight, led by an indomitable Squadron Commander, is one of the most outstanding exhibitions of personal bravery and gallantry that has ever come to his attention in the records of the past or present".

Commander Waldron was awarded the Navy Cross for heroism posthumously. The Battle of Midway has been termed the turning point in the Pacific Theatre in WW II and was the subject of an epic motion picture film. Lt. Comdr. John C. Waldron, USN was buried in St. John's Cemetery 4 North Section 49.
