observed British military tactics, gaining a keen insight into their strengths and weaknesses that proved invaluable during the Revolution. He demonstrated his toughness and courage in the most difficult situations, including disasters and retreats. He developed a command presence—given his size, strength, stamina, and bravery in battle, he appeared to soldiers to be a natural leader and they followed him without question. Washington learned to organize, train, and drill, and discipline his companies and regiments. From his observations, readings and conversations with professional officers, he learned the basics of battlefield tactics, as well as a good understanding of problems of organization and logistics. He gained an understanding of overall strategy, especially in locating strategic geographical points. He developed a very negative idea of the value of militia, who seemed too unreliable, too undisciplined, and too short-term compared to regulars. On the other hand, his experience was limited to command of at most 1,000 men, and came only in remote frontier conditions that were far removed from the urban situations he faced during the Revolution at Boston, New York, Trenton and Philadelphia. Political resistance In December 1758 Washington resigned his military commission, and spent the next 16 years as a wealthy Virginia plantation owner; as such he also served in the Virginia House of Burgesses. Although he expressed opposition to the 1765 Stamp Act, the first direct tax on the colonies, he did not take a leading role in the growing colonial resistance until protests of the Townshend Acts (enacted in 1767) became widespread. In May 1769, Washington introduced a proposal, drafted by his friend George Mason, calling for Virginia to boycott British goods until the Acts were repealed. Parliament repealed the Townshend Acts in 1770, and, for Washington at least, the crisis had passed. However, Washington regarded the passage of the Intolerable Acts in 1774 as "an Invasion of our Rights and Privileges". In July 1774, he chaired the meeting at which the "Fairfax Resolves" were adopted, which called for, among other things, the convening of a Continental Congress. In August, Washington attended the First Virginia Convention, where he was selected as a delegate to the First Continental Congress. As tensions rose in 1774, he assisted in the training of county militias in Virginia and organized enforcement of the boycott of British goods instituted by the Congress. Major roles General Washington, the Commander in Chief, assumed five main roles during
