On the 14th April, congress laid an embargo on all ships and vessels of the United States during the space of ninety days, with the view of lessening the number that would be at the mercy of England when war was finally declared, and also of manning efficiently their ships of war and privateers.

By the end of May their fastest merchant vessels were converted into cruisers, ready to start at a short notice.

On the 18th of June, before the revocation of the orders in council was known in the United States, a declaration of war was carried in the house of representatives by seventy-nine to forty-nine votes, its supporters being chiefly from the western and southern states to Pennsylvania inclusive, while the advocates for peace were principally from the northern and eastern states.[44] _Sir George Prevost to Major-General Brock_.
QUEBEC, January 22, 1812.
It is the opinion of the adjutant-general that you will not wish to avail yourself of the conditional leave of absence I have received authority to grant you.

I shall hear with particular satisfaction that Baynes is not mistaken, as I value your services highly.
If it be the disposition of government to employ Major-General Sheaffe, the death of Major-General Balfour, at Fredericton, and the absence of Major-General Wilder, affords the opportunity of doing so without depriving me of your assistance at this critical period of affairs.
_Colonel Baynes to Major-General Brock, at York._ QUEBEC, January 23, 1812[45] Sir George Prevost has commissioned me to inform you that by the October mail, which arrived two days ago, he received a letter from the adjutant-general, authorizing him to permit your return to England for the purpose of being employed on the continent, and sanctioning his appointing Major-General Sheaffe to succeed you on the staff in Canada.

But Sir George, viewing the intention of the commander-in-chief as instigated solely by a desire to promote your wishes and advantage, and having learnt from me that from the tenor of your recent correspondence I was led to believe that you would prefer retaining your present charge, he has directed me to inform you of the circumstance by a private letter, which will enable you to canvass the subject with more freedom than an official communication would admit of.
