While steaming through the river roughly north of
Chenglin at exactly 09:00 on 17 January, the 200
long ton (200
tonne)
Monocacy was fired on from both sides of the river by Chinese troops ashore. Delano quickly ordered his men to alter course and raise the largest American flag aboard. The first shot struck the
jackstaff and was followed by a volley from an estimated 200 rifles. Two shots hit the bridge, so at 09:01 the Americans returned fire with
small arms. Chinese forces were spread out for along the river and their shots increased as the Americans continued on, but by 09:05 most of the rifles were silent, except for some sporadic sniping.
Chief Yeoman Howard LeRoy O'Brien was hit by one of these sporadic shots and fell to the deck dead. Because of this, the skipper ordered his men to return fire with the battery of 6-pounders at 09:25, and five minutes later all was quiet. After shooting only six or seven shells and about 3,000 bullets, the attackers retreated.
Monocacy was hit about eighty times and two American sailors were wounded by Chinese fire, one of them seriously. During the engagement, a Japanese steamer was heading downriver and was fired on, but the Americans prevented her from being damaged by providing covering fire. ==See also==
