I have had a request for more coverage of the battle, so I had to comply else the Hessians would over run my blog.
On December 21, about 600 of Griffin’s troops overwhelmed a guard outpost of the 42nd located about one mile south of Blackhorse at Petticoat Bridge. On the evening of December 22, Washington’s adjutant, Joseph Reed, went to Mount Holly and met with Griffin. Griffin had written to Reed, requesting small field pieces to assist in their actions, and Reed, who had been discussing a planned attack on Rall’s men in Trenton with Washington, wanted to see if Griffin’s company could participate in some sort of diversionary attack. Griffin was ill, and his men poorly equipped for significant action, but they apparently agreed to some sort of actions the next day.
On the morning of December 23, von Donop brought about 3,000 troops (the 42nd British (Highland) Regiment and the Hessian Grenadier battalions Block and Linsing) to Petticoat Bridge where they overwhelmed Griffin’s men. Griffin’s troops retreated to Mount Holly where von Donop reported scattering about 1,000 men near the town’s meeting house. Jäger Captain Johann Ewald reported that “some 100 men” were posted on a hill “near the church”, who “retired quickly” after a few rounds of artillery were fired. Griffin, whose troops had occupied Mount Holly, slowly retreated to their fortified position on the hill, following which the two sides engaged in ineffectual long-range fire.
