1801. Despite his complaints that the house was too big ("big enough for two emperors, one pope, and the grand lama in the bargain"), Jefferson considered how the White House might be added to. With Benjamin Henry Latrobe, he helped lay out the design for the East and West Colonnades, small wings that help conceal the domestic operations of laundry, a stable and storage. Today, Jefferson's colonnades link the residence with the East and West Wings. In 1814, during the War of 1812, the White House was set ablaze by British forces during the Burning of Washington, in retaliation for the American destruction of York, Port Dover and other towns in Upper Canada; much of Washington was affected by these fires as well. Only the exterior walls remained, and they had to be torn down and mostly reconstructed because of weakening from the fire and subsequent exposure to the elements, except for portions of the south wall. Of the numerous objects taken from the White House when it was ransacked by British forces, only three have been recovered. White House employees and slaves rescued a copy of the Lansdowne portrait, and in 1939 a Canadian man returned a jewelry box to President Franklin Roosevelt, claiming that his grandfather had taken it from Washington; in the same year, a medicine chest that had belonged to President Madison was returned by the descendants of a Royal Navy officer. Some observers allege that most of the spoils of war taken during the sack were lost when a convoy of British ships led by HMS Fantome sank en route to Halifax off Prospect during a storm on the night of November 24, 1814, even though Fantome had no involvement in that action. After the fire, President James Madison resided in the Octagon House from 1814 to 1815, and then in the Seven Buildings from 1815 to the end of his term. Meanwhile, both Hoban and Latrobe contributed to the design and oversight of the reconstruction, which lasted from 1815 until 1817. The south portico was constructed in 1824 during the James Monroe administration. The north portico was built in 1830. Though Latrobe proposed similar porticos before the fire in 1814, both porticos were built as designed by Hoban. An elliptical portico at Château de Rastignac in La Bachellerie, France, with nearly identical curved stairs, is speculated as the source of inspiration due to its
