1717: At about 8:00 p.m. on Wednesday, 17th July, 1717, King George I and several aristocrats boarded a royal barge at Whitehall Palace for an excursion up the Thames toward Chelsea. The rising tide propelled the barge upstream without rowing. Another barge provided by the City of London contained about fifty musicians who premiered performed George Frideric Handel's Water Music. Many other Londoners also took to the river to hear the concert as, scored for a relatively large orchestra, the Water Music is particularly suitable for outdoor performance.

1944: The Port Chicago disaster occurs at around 22:00 hrs at the Port Chicago Naval Magazine in Port Chicago, California, U.S.A., when munitions on board the liberty ship SS 'E. A. Bryan' are detonated by an initial explosion during loading. The second, more powerful explosion created a fireball which was seen for miles - an Army Air Force pilot flying in the area reported that the fireball was 3 miles in diameter.
Chunks of glowing hot metal and burning ordnance were flung over 12,000 ft into the air. The 'E. A. Bryan' was completely destroyed and the 'Quinault Victory' (docked at the same pier) was blown out of the water, torn into sections and thrown in several directions; the stern landed upside down in the water 500 ft away. The Coast Guard fire boat CG-60014-F was thrown 600 ft upriver, where it sank. The pier - along with its boxcars, locomotive, rails, cargo and men - was blasted into pieces.
All 320 of the men on duty at the pier died instantly, and 390 civilians and military personnel were injured, many seriously. Among the dead were all five Coast Guard personnel posted aboard the fire barge. African Americans hurt and killed totaled 202 dead and 233 injured, which accounted for 15% of all African-American naval casualties during World War II.
