THOSE who expect to reap the blessings of freedom, must, like men, undergo the fatigues of supporting it. The event of yesterday was one of those kind of alarms which is just sufficient to rouse us to duty, without being of consequence enough to depress our fortitude. It is not a field of a few acres of ground, but a cause, that we are defending, and whether we defeat the enemy in one battle, or by degrees, the consequences will be the same. Look back at the events of last winter and the present year, there you will find that the enemy's successes always contributed to reduce them. What they have gained in ground, they paid so dearly for in numbers, that their victories have in the end amounted to defeats. We have always been masters at the last push, and always shall be while we do our duty. Howe has been once on the banks of the Delaware, and from thence driven back with loss and disgrace: and why not be again driven from the Schuylkill? His condition and ours are very different. He has everybody to fight, we have only his one army to cope with, and which wastes away at every engagement: we can not only reinforce, but can redouble our numbers; he is cut off from all supplies, and must sooner or later inevitably fall into our hands. Shall a band of ten or twelve thousand robbers, who are this day fifteen hundred or two thousand men less in strength than they were yesterday, conquer America, or subdue even a single state? The thing cannot be, unless we sit down and suffer them to do it. Another such a brush, notwithstanding we lost the ground, would, by still reducing the enemy, put them in a condition to be afterwards totally defeated. Could our whole army have come up to the attack at one time, the consequences had probably been otherwise; but our having different parts of the Brandywine creek to guard, and the uncertainty which road to Philadelphia the enemy would attempt to take, naturally afforded them an opportunity of passing with their main body at a place where only a part of ours could be posted; for it must strike every thinking man with conviction, that it requires a much greater force to oppose an enemy in several places, than is sufficient to defeat him in any one place. Men who are sincere in defending their freedom, will always feel concern at every circumstance which seems to make against them; it is the natural and honest consequence of all affectionate attachments, and the want of it is a vice. But the dejection lasts only for a moment; they soon rise out of it with additional vigor; the glow of hope, courage and fortitude, will, in a little time, supply the place of every inferior passion, and kindle the whole heart into heroism.
