At two o'clock all the fighting boys of the Temple Grammar School, and as many recruits as we could muster, lay behind the walls of Fort Slatter, with three hundred compact snowballs piled up in pyramids, awaiting the approach of the enemy. The enemy was not slow in making his approach--fifty strong, headed by one Mat Ames. Our forces were under the command of General J. Harris. Before the action commenced, a meeting was arranged between the rival commanders, who drew up and signed certain rules and regulations respecting the conduct of the battle. As it was impossible for the North-Enders to occupy the fort permanently, it was stipulated that the South-Enders should assault it only on Wednesday and Saturday afternoons between the hours of two and six. For them to take possession of the place at any other time was not to constitute a capture, but on the contrary was to be considered a dishonorable and cowardly act. The North-Enders, on the other hand, agreed to give up the fort whenever ten of the storming party succeeded in obtaining at one time a footing on the parapet, and were able to hold the same for the space of two minutes. Both sides were to abstain from putting pebbles into their snow-balls, nor was it permissible to use frozen ammunition. A snow-ball soaked in water and left out to cool was a projectile which in previous years had been resorted to with disastrous results. These preliminaries settled, the commanders retired to their respective corps. The interview had taken place on the hillside between the opposing lines. General Harris divided his men into two bodies; the first comprised the most skilful marksmen, or gunners; the second, the reserve force, was composed of the strongest boys, whose duty it was to repel the scaling parties, and to make occasional sallies for the purpose of capturing prisoners, who were bound by the articles of treaty to faithfully serve under our flag until they were exchanged at the close of the day. The repellers were called light infantry; but when they carried on operations beyond the fort they became cavalry. It was also their duty, when not otherwise engaged, to manufacture snow-balls. The General's staff consisted of five Templars (I among the number, with the rank of Major), who carried the General's orders and looked after the wounded. General Mat Ames, a veteran commander, was no less wide-awake in the disposition of his army. Five companies, each numbering but six men, in order not to present too big a target to our sharpshooters, were to charge the fort from different points, their advance being covered by a heavy fire from the gunners posted in the rear. Each scaler was provided with only two rounds of ammunition, which were not to be used until he had mounted the breastwork and could deliver his shots on our heads. The drawing below represents the interior of the fort just previous to the assault. Nothing on earth could represent the state of things after the first volley.
