Monmouth, Battle of. Was fought June 28, 1778, between the Revolutionary forces under Gen. Washington and the British under Sir Henry Clinton. Gen. Washington, whose army of about 12,000 men was encamped at Valley Forge, being informed of the intention of the enemy to evacuate Philadelphia and proceed to New York, placed his forces in a condition to march immediately in pursuit. Accordingly, when intelligence of the evacuation reached him, he broke up his encampment, and detaching a small force under Gen. Arnold to take possession of Philadelphia, marched rapidly with his whole army toward the Delaware. On the morning of June 28 the advance of the Colonial army, under Gen. Lee, became engaged with the enemy’s rear on the plain near Monmouth Court-house, in New Jersey; but the English line being soon reinforced, the Americans were compelled to give way, upon which Lee ordered a retreat. Gen. Washington, who was riding ahead of the main body of his army, met the retreating force, and peremptorily ordered Lee to reform his troops and hold his position. This he for a time partially effected, but was being again driven back, when the main body of the army arrived to his assistance. The battle now became general, and under the inspiring influence of their commander-in-chief the Americans fought with such desperate resolution that the British were at length obliged to give way. Washington made preparations to follow up his advantage, but owing to the broken character of the ground, and twilight coming on before a proper disposition of his troops could be made, the attack was postponed until next morning. When morning dawned, however, it was found that Sir Henry Clinton with his whole force had retreated during the darkness of the night toward Sandy Hook, and Washington, on account of the heat of the weather and the fatigue of his men, did not pursue them. This was one of the most severely contested battles of the war. The American loss was 227 killed and wounded, the English was a little greater.
