Breaking the line

   Crossing the Tee did not work in sailing ship days, partly because sailing ships could not sail into the wind.  At best a square rigged sailing warship might point up 35 degrees into the wind, leaving 55 degrees to go before being head to wind.  In short, there was 110 degrees of course where sailing fleets could not sail, out of 360 degrees for a full circle.  Whereas a later steam fleet could steam any course the admiral desired.

   Sailing fleets sailed and fought in line ahead, at least after the British took out the Spanish Armada back in Queen Elizabeth’s time.  In fact the British Fighting Instructions to its captains were very firm, not to say fierce about staying in line, not breaking out the line for any reason whatsoever, on pain of court martial.  If my fleet is in line ahead I can do the enemy a lot more damage because all of my guns bear on the enemy.  Not only that, I will take less damage from enemy fire hitting my sides, which are stout and nearly shot proof, than a single broadside delivered to the vulnerable stern, one of which can knock all the fight out of a ship. 

    Sailing ship actions depended upon the wind.  The British preferred to hold the weather gauge, (to be to windward of the enemy)  This permitted them to control the action, they could engage when they felt the time was ripe, or not engage but keep the enemy at battle stations for days.  The French preferred to hold the lee gauge (to be down wind of the enemy).  This permitted a French admiral, who saw his fleet getting beat, to order a turn downwind, a square rigger’s best point of sailing, and get away. 

   If both sides stayed in line ahead and fired on each other, in many cases neither side could do much harm to the enemy.  Lot of powder got burned, lot of victory claims were made, but nothing was decided.

   Nelson understood this before Trafalgar.  He decided to try “breaking” the enemy line, having a lot of his ships get thru the enemy line and then bring two broadsides to bear on each enemy ship, the broadside of the ships that broke thru the line and the ships that didn’t.  This was totally against Fighting Instructions, hence Nelson’s famous comment    “No captain can do very wrong if he places his ship alongside that of the enemy.”  At Trafalgar Nelson in 100 gun Victory broke the French line in one place and Cuthbert Collingwood, his second in command broke the French line in another place. The result was annihilation of the French fleet, handing control of the sea to the British for the rest of the Napoleonic wars.
