Johann De Kalb continental army officer worked closely with Washington and killed at counterattack
Step-by-step explanation:
De Kalb joined the continental army from France with the rank of major general. De Kalb worked with Lafayette before and travelled to Philadelphia to meet the continental congress.
He then joined Washington and worked with him. Although, Washington's enemies too jealous of his loyal commander in chief planned to remove him by proposing that Lafayette should lead an invasion in Canada, with De Kalb.
De Kalb served with Washington for a long time as a loyal commander until this happened.
