context_page_description: The Battle of Trafalgar was a naval engagement fought by the British Royal Navy against the combined fleets of the French and Spanish Navies during the War of the Third Coalition of the Napoleonic Wars.
  As part of an overall French plan to combine all French and allied fleets to take control of the English Channel and thus enable Napoleon's Grande Armée to invade England, French and Spanish fleets under French Admiral Villeneuve sailed from the port of Cádiz in the south of Spain on 18 October 1805. They encountered the British fleet under Admiral Lord Nelson, recently assembled to meet this threat, in the Atlantic Ocean along the southwest coast of Spain, off Cape Trafalgar, near the town of Los Caños de Meca. Villeneuve was uncertain about engaging the British, and the Franco-Spanish fleet failed to fully organize. In contrast, Nelson was decisive, organizing the British fleet into two columns sailing straight into the enemy to pierce its wavering lines.
  In a particularly fierce battle, 27 British ships of the line fought 33 French and Spanish ships of the line.
context_section_description: The prevailing tactical orthodoxy at the time involved manoeuvring to approach the enemy fleet in a single line of battle and then engaging broadside in parallel lines. In previous times, fleets had usually engaged in a mixed mêlée of chaotic one-on-one battles. One reason for the development of the line of battle system was to facilitate control of the fleet: if all the ships were in line, signalling in battle became possible. The line also allowed either side to disengage by breaking away in formation; if the attacker chose to continue, their line would be broken as well. This often led to inconclusive battles, or allowed the losing side to minimise its losses; but Nelson wanted a conclusive action, giving his well-trained crews a chance to fight ship to ship.
  Nelson's solution to the problem was to cut the opposing line in three. Approaching in two columns, sailing perpendicular to the enemy's line, one towards the centre of the opposing line and one towards the trailing end, his ships would surround the middle third, and force them to fight to the end. Nelson hoped specifically to cut the line just in front of the French flagship, Bucentaure; the isolated ships in front of the break would not be able to see the flagship's signals, which he hoped would take them out of combat while they re-formed. This echoed the tactics used by Admiral Duncan at the Battle of Camperdown and Admiral Jervis at the Battle of Cape St Vincent, both in 1797.
  The plan had three principal advantages. First, the British fleet would close with the Franco-Spanish as quickly as possible, preventing their escape. Second, it would quickly bring on a mêlée and frantic battle by breaking the Franco-Spanish line and inducing a series of individual ship-to-ship actions, in which the British were likely to prevail. Nelson knew that the superior seamanship, faster gunnery and better morale of his crews were great advantages. Third, it would bring a decisive concentration on the rear of the Franco-Spanish fleet. The ships in the van of the enemy fleet would have to turn back to support the rear, which would take a long time. Additionally, once the Franco-Spanish line had been broken, their ships would be relatively defenceless against powerful broadsides from the British fleet, and it would take them a long time to reposition to return fire.
  The main drawback of attacking head-on was that as the leading British ships approached, the Franco-Spanish Combined Fleet would be able to direct raking broadside fire at their bows, to which they would be unable to reply. To lessen the time the fleet was exposed to this danger, Nelson had his ships make all available sail (including stunsails), yet another departure from the norm. He was also well aware that French and Spanish gunners were ill-trained and would have difficulty firing accurately from a moving gun platform. The Combined Fleet was sailing across a heavy swell, causing the ships to roll heavily and exacerbating the problem. Nelson's plan was indeed a gamble, but a carefully calculated one.
  During the period of blockade off the coast of Spain in October, Nelson instructed his captains, over two dinners aboard Victory, on his plan for the approaching battle. The order of sailing, in which the fleet was arranged when the enemy was first sighted, was to be the order of the ensuing action so that no time would be wasted in forming two lines. The first, led by his second-in-command Vice-Admiral Cuthbert Collingwood, was to sail into the rear of the enemy line, while the other, led by Nelson, was to sail into the centre and vanguard. In preparation for the battle, Nelson ordered the ships of his fleet to be painted in a distinctive yellow and black pattern (later known as the Nelson Chequer) that would make them easy to distinguish from their opponents.
  Nelson was careful to point out that something had to be left to chance. Nothing is sure in a sea battle, so he left his captains free from all hampering rules by telling them that "No captain can do very wrong if he places his ship alongside that of the enemy
