Philadelphia, which had recently suffered for want of bare necessities, now relapsed into gay indulgence.
Arnold lived extravagantly.

He played a conspicuous part in society and, a widower of thirty-five, was successful in paying court to Miss Shippen, a young lady of twenty, with whom, as Washington said, all the American officers were in love.
Malignancy was rampant and Arnold was pursued with great bitterness.
Joseph Reed, the President of the Executive Council of Pennsylvania, not only brought charge against him of abusing his position for his own advantage, but also laid the charges before each State government.

In the end Arnold was tried by court-martial and after long and inexcusable delay, on January 26, 1780, he was acquitted of everything but the imprudence of using, in an emergency, public wagons to remove private property, and of granting irregularly a pass to a ship to enter the port of Philadelphia.

Yet the court ordered that for these trifles Arnold should receive a public reprimand from the Commander-in-Chief.
Washington gave the reprimand in terms as gentle as possible, and when, in July, 1780, Arnold asked for the important command at West Point, Washington readily complied probably with relief that so important a position should be in such good hands.
The treason of Arnold now came rapidly to a head.

The man was embittered.
