(CNN) -- Britain's Chris Froome won the 17th stage of the Tour de France on Wednesday to strengthen his grip on the yellow jersey. Froome completed Wednesday's 32-kilometer time trial in 51 minutes 33 seconds, nine seconds ahead of Spain's Alberto Contador with his compatriot Joaquim Rodriguez Oliver finishing a further second behind in third. "I couldn't believe it when I got over the line and saw I had the fastest time," Froome said after his third stage win of this year's tour. "I went into today thinking I was going to try and limit my losses, thinking about the days to come now. So to go through the finish line with the fastest time, I really didn't see that coming." On mountainous terrain along a frequently twisting route most of the riders opted for their traditional road bikes over the more aerodynamic machines used in time trials. But Froome opted to use both on the stage, switching to a time trial model for the final 12-kilometer descent. The swap proved decisive as the Briton clawed back a 20-second advantage Contador had built up earlier in the stage. The Spaniard now moves up to second overall, four minutes 34 seconds behind Froome with just four stages remaining. Contador's Saxo-Tinkoff teammate Roman Kreuziger is now third and trails Froome by four minutes and 51 seconds. Thursday sees the riders tackle the gruelling 172.5-kilometer 18th stage which concludes with a double ascent of Alpe d'Huez over the last 60 kilometers.

In early March, the administration postponed action on proposals for increasing aid to the Northern Alliance and the Uzbeks. Rice noted at the time that a more wide-ranging examination of policy toward Afghanistan was needed first. She wanted the review very soon. Rice and others recalled the President saying, "I'm tired of swatting at flies." The President reportedly also said,"I'm tired of playing defense. I want to play offense. I want to take the fight to the terrorists." President Bush explained to us that he had become impatient. He apparently had heard proposals for rolling back al Qaeda but felt that catching terrorists one by one or even cell by cell was not an approach likely to succeed in the long run. At the same time, he said, he understood that policy had to be developed slowly so that diplomacy and financial and military measures could mesh with one another. Hadley convened an informal Deputies Committee meeting on March 7, when some of the deputies had not yet been confirmed. For the first time, Clarke's various proposals-for aid to the Northern Alliance and the Uzbeks and for Predator missions-went before the group that, in the Bush NSC, would do most of the policy work. Though they made no decisions on these specific proposals, Hadley apparently concluded that there should be a presidential national security policy directive (NSPD) on terrorism. Clarke would later express irritation about the deputies' insistence that a strategy for coping with al Qaeda be framed within the context of a regional policy. He doubted that the benefits would compensate for the time lost. The administration had in fact proceeded with Principals Committee meetings on topics including Iraq and Sudan without prior contextual review, and Clarke favored moving ahead similarly with a narrow counterterrorism agenda. But the President's senior advisers saw the al Qaeda problem as part of a puzzle that could not be assembled without filling in the pieces for Afghanistan and Pakistan. Rice deferred a Principals Committee meeting on al Qaeda until the deputies had developed a new policy for their consideration.

Alexander earned the epithet "The Great" due to his unparalleled success as a military commander. He never lost a battle, despite typically being outnumbered. This was due to use of terrain, phalanx and cavalry tactics, bold strategy, and the fierce loyalty of his troops. The Macedonian phalanx, armed with the sarissa, a spear 6 metres (20 ft) long, had been developed and perfected by Philip II through rigorous training, and Alexander used its speed and maneuverability to great effect against larger but more disparate Persian forces. Alexander also recognized the potential for disunity among his diverse army, which employed various languages and weapons. He overcame this by being personally involved in battle, in the manner of a Macedonian king. In his first battle in Asia, at Granicus, Alexander used only a small part of his forces, perhaps 13,000 infantry with 5,000 cavalry, against a much larger Persian force of 40,000. Alexander placed the phalanx at the center and cavalry and archers on the wings, so that his line matched the length of the Persian cavalry line, about 3 km (1.86 mi). By contrast, the Persian infantry was stationed behind its cavalry. This ensured that Alexander would not be outflanked, while his phalanx, armed with long pikes, had a considerable advantage over the Persian's scimitars and javelins. Macedonian losses were negligible compared to those of the Persians. At Issus in 333 BC, his first confrontation with Darius, he used the same deployment, and again the central phalanx pushed through. Alexander personally led the charge in the center, routing the opposing army. At the decisive encounter with Darius at Gaugamela, Darius equipped his chariots with scythes on the wheels to break up the phalanx and equipped his cavalry with pikes. Alexander arranged a double phalanx, with the center advancing at an angle, parting when the chariots bore down and then reforming. The advance was successful and broke Darius' center, causing the latter to flee once again. When faced with opponents who used unfamiliar fighting techniques, such as in Central Asia and India, Alexander adapted his forces to his opponents' style. Thus, in Bactria and Sogdiana, Alexander successfully used his javelin throwers and archers to prevent outflanking movements, while massing his cavalry at the center.

Duane was hungry, but he hurried through the ample supper that was set before him, urged on by curiosity and astonishment. The only way he could account for his presence there in a ranger's camp was that MacNelly hoped to get useful information out of him. Still that would hardly have made this captain so eager. There was a mystery here, and Duane could scarcely wait for it to be solved. While eating he had bent keen eyes around him. After a first quiet scrutiny the rangers apparently paid no more attention to him. They were all veterans in service--Duane saw that--and rugged, powerful men of iron constitution. Despite the occasional joke and sally of the more youthful members, and a general conversation of camp-fire nature, Duane was not deceived about the fact that his advent had been an unusual and striking one, which had caused an undercurrent of conjecture and even consternation among them. These rangers were too well trained to appear openly curious about their captain's guest. If they had not deliberately attempted to be oblivious of his presence Duane would have concluded they thought him an ordinary visitor, somehow of use to MacNelly. As it was, Duane felt a suspense that must have been due to a hint of his identity.
